Analysis of the spectrum made it possible to assign several dozen transitions in the nu6, nu8, and nu5 vibrational states and to determine the rotational and centrifugal distortion constants. The derived parameters of the nu6 state allowed four optically pumped laser transitions to be assigned. In addition, the ground state parameters for DCOOH and D13COOH have been improved and for the first time those for DC18OOH and DCO18OH have been obtained.

The 7 1 and 9 1 vibrational states of deuterated species of formic acid molecule DCOOH have been ... more The 7 1 and 9 1 vibrational states of deuterated species of formic acid molecule DCOOH have been recorded by a FTIR spectrometer in the region 450-820 cm À1 at a resolution of 0:00125 cm À1 and a millimeter wave spectrometer. In the analysis microwave transitions from literature were used in addition to 14 835 assigned IR and 114 millimeter wave lines in the 7 1 and 9 1 vibrational states. The analysis resulted in band origins, rotational, centrifugal distortion, and eight interaction parameters of the Coriolis coupled 7 1 and 9 1 vibrational states. RMS deviation of the fit was 0:000176 cm À1 for the IR data and the maximum values of J and K a quantum numbers in the fit were 64, 28 and 64, 30 for 7 1 and 9 1 states, respectively.

The Fourier transform gas-phase infrared spectra of the Coriolis-perturbed nu(6) and nu(8) bands ... more The Fourier transform gas-phase infrared spectra of the Coriolis-perturbed nu(6) and nu(8) bands of deuterated formic acid DCOOH were measured with a resolution of ca. 0.003 cm(-1). Combined analysis of the 8977 IR transitions and all the available rotational data (from literature) in the ground state, as well as in the excited vibrational states v(6) = 1 and v(8) = 1 was carried out. The Coriolis coupling terms were determined and improved sets of rotational and centrifugal distortion parameters for the ground and excited vibrational states were obtained. The determined band centers are nu(0) (nu(8)) = 873.385046(12) cm(-1) and nu(0) (nu(6)) = 970.8889551(46) cm(-1). Copyright 1999 Academic Press.

These include transitions of the cis-rotamer, the analysis of which is reported here. The data for the ground state could be significantly extended (546 lines), and the first information on rotational structure in vibrationally excited cis-HCOOH in the v 9 Z1 and v 7 Z1 states was obtained. Finally, transitions of cis-H 13 COOH in the ground state were also observed. The rotational parameters resulting from the analysis of each of these spectra are reported, together with an initial determination of the Coriolis coupling parameters for the 7 1 /9 1 resonance interaction, an experimental force field calculation and a new structure determination. q

For CH2DI ν6' appears as a hybrid a/b-type band and ν6'' as a c-type band. For CHD2I the corresponding types are hybrid a/c and b. We have been able to assign more than 12 000 transitions in the case of CH2DI and over 11 000 transitions in the case of CHD2I. The upper and ground state parameters have been obtained by fitting these transitions to the A reduced Watson's Hamiltonian. The interactions between the states v6'=1 and v6''=1 have also been investigated.

The submillimeter-wave spectra of the ground, v3 = 1, and v6 = 1 vibrational states of CHF 3 and ... more The submillimeter-wave spectra of the ground, v3 = 1, and v6 = 1 vibrational states of CHF 3 and also of the ground state of 13CHF 3 were measured in the frequency range from 280 to 500 GHz. The A+- A- splittings of the K - l = 3 transitions in the v6 = 1 excited state were observed. Improved values for the rotational constants, along with values for a number of other molecular parameters, have been obtained by a least-squares fit of the experimental data. The quartic distortion constants in the v6 = 1 state, DJ = 11.4150 ± 0.0037 kHz and DJK = -18.3080 ± 0.0044 kHz, were found to be consistent with those in the ground state.

Rotational-electronic transitions of the two previously unstudied 4p-5s and 5p-6s,v = 0-0, bands of (40)ArH were measured and assigned in the 6060 and 3770 cm(-1) regions, respectively. A simultaneous fit of the emission transitions of the 4p-5s and 5p-6s bands and an extended set of transitions of the 6s-4p band observed by Dabrowski, Tokaryk, and Watson [J. Mol. Spectrosc. 189, 95 (1998)] and remeasured in the present work yielded consistent values of the spectroscopic parameters of the electronic states under investigation. In the branch of the 4p-5s band with transitions of type (Q)Q(f(3)e) we observed a narrowing in the linewidths with increasing rotational quantum number N. The rotational dependence of the linewidth is caused by predissociation of the 5s state by the repulsive ground 4s state through homogeneous coupling and changes in overlap integrals of the vibrational wave functions with the rotational level. Analysis was based on the Fermi's golden rule approximation model. In the 4p-5s band region a vibrational sequence ofv(')-v(")=1-1, 2-2, and 3-3 were recorded and a number of transitions belonging to the strongest (Q)Q(f(3)e) form branch of the 1-1 band were analyzed.

Rotational transitions in the millimeter wave region were measured and included in the analysis. As in the parent species, there is a strong Coriolis interaction between the 7 1 and 9 1 states. The corresponding IR bands of the parent species have been remeasured and new MMW transitions recorded. The analysis of the spectra for the two species provides an opportunity to consider a reduction of the Hamiltonian employed for the analysis of this type of interacting system of states. Parameters with low correlations could be obtained. Several interstellar features coincide with transitions predicted from these parameters.

Rotational and centrifugal distortion parameters of the 9 1 vibrational states have been obtained or improved.

During one cycle of the He-Ne laser fringe, 30 data points are recorded with a preset time interval of 2 or 3 ls. The present system is applicable for any commercial continuously scanning interferometer. This method is applied to a pulsed discharge in an Ar and H 2 mixture to observe time profiles of Ar, ArH, and ArH þ emission spectra. Pulsed afterglow was found to be an efficient source for the ArH radical. ArH and ArH þ showed different time profiles, depending on the production mechanism.

More than 10 000 lines have been assigned and fitted with a RMS deviation of 0.00024 cm À1 . The band centers, as well as the rotational, quartic and sextic centrifugal distortion parameters and 6 interaction parameters have been determined.

For the first time, all the transitions were identified on the basis of directly calculated frequencies. These results were obtained through the use of a new effective torsional-rotational Hamiltonian. Its parameters were calculated based on the frequencies of all earlier known and new transitions of microwave and submillimeter-wave spectra of the ground torsional-vibrational state of methanol The root-mean-square deviation is 710 kHz (800 lines) for the main isotopomer, 144 kHz (370 lines) for CDrOH, and 316 kHz ( 150 lines) for CDSOD.
