For the outermost 2~1 , 2~1 , and 2~2 states the effects are comparible with the earlier UPS-results. For the inner valence levels the isotope effects are demonstratedfor the first time.

Researchers have called this to bridge the credibility gap. Getting one actor committed to the project will help establishing credibility to reach out to other actors (Birley and Norburn 1985). Further research has proven that personal relationships are often the factor that enables the first transactions and the founders of the firm are using their prior credibility in the new firm (Kowalkowski et al 2005). From case studies and interviews with different stakeholders we found that companies using media as a strategy to launch their new concept, and managing to get good coverage, equals this to having prior relationships with customers and other stakeholders. It even increases the understanding of the new concept, and the firm does not need to explain their business idea and model every time the meet a new customer/stakeholder. Furthermore, coverage inhibits second entrants of getting media coverage because the newness is gone. On the other hand, media coverage might help create exaggerated expectations or alert response from competitors. Therefore it is not always clear whether news media coverage is helpful or not. We suggest that it will often be a plausible strategy to get media coverage in very early stages of a project, when the credibility gap is large and the risk of exaggerating expectations are low. This will also help to develop media relations that will be useful as the firm develops.

The experimental X-ray data of 1,1-bis(4-formylbenzyl)-4,4'-bipyridinium bis(hexaflurophosphate) was used in molecular modeling studies. The optimization of isolated 1,1-bis(4-formylbenzyl)-4,4'-bipyridinium (BFBP) molecule without counter ions PF6(-) does not lead to significant changes of dihedral angles, thus the molecular conformation does not depend on interactions with the counter ions. The structural optimization and normal mode analysis were performed for G2 on the basis of the density functional theory (DFT). The calculated geometrical parameters and harmonic vibrational frequencies are predicted in a good agreement with the experimental data. It was found that G2 has a kind of "egg timer" structure with planar OC6H4CHNN(CH3) fragments and slightly non-planar cyclotriphosphazene core. The experimental IR and Raman spectra of G2 were interpreted by means of potential energy distribution.

An information package—INFOPAC—is attached to each new research project receiving financial support from two research-funding organizations in Sweden. Project leaders are offered one day of training in both theories concerning research dissemination and practical application. The first task for the participants in the training is to write a press release and send it to chosen media. An information consultant attached to the projects then measures the outcome. The information consultant also follows up and helps the course participants during the period of the project funding. The trial with INFOPAC has been in progress for three years, and the results achieved so far are reported in this article and placed in their theoretical context.

High resolution combined with the additional information given by comparing spectra taken at different angles permits detailed analysis of the vibrational structure. 6-values are given for all vibrational components hitherto observed in the photoelectron spectrum of the & A, fl and c electronic bands. Single excitations of the vs mode with vibrational energies, 181 meV in the a-state and 279 meV in the B&ate are reported. The peak at 366meV vibrational energy in the &tate is reinterpreted as a single va excitation. The j-values of the most intense peaks are also measured using Ne(I) (16.67 and 16.66 eV), Ne(II) (26.36 and 26.96 eV) and He(J) (40.81) resonance radiations.

High resolution x-ray excited (1487 eV photon energy) shake-up spectra of C6H6, C6H5OH, and C6H5C... more High resolution x-ray excited (1487 eV photon energy) shake-up spectra of C6H6, C6H5OH, and C6H5CH2OH are presented. A large number of new structures are observed and an interpretation is made, for the first π–π* shake-up states, using INDO/CI calculations. The C1s shake-up spectra of C6H6 and C6H5CH2OH are similar but differ substantially from the C6H5OH C1s shake-up spectrum. This is explained as originating from the conjugation of the lone pair O2p orbitals in the latter case. It is also shown that the inelastic scattering excitations fall exactly under the shake-up spectrum. This observation has important consequences for the assignment of shake-up spectra from aromatic ring molecules in the solid phase.

Potential energy surfaces, properties, and spectra of singlet (X ' A ,) and triplet (a3B2) ozone ... more Potential energy surfaces, properties, and spectra of singlet (X ' A ,) and triplet (a3B2) ozone are investigated by means of MCSCF/MCLR analytical response theory calculations. MCSCF analytical gradients and Hessians are used to locate equilibrium and transition-state structures and to obtain associated vibrational and rotational constants, infrared intensities, and dipole moments. By means of MC linear response functions, electronic excitation energies, and oscillator strengths, static and dynamic polarizabilities as well as dispersion (C,) coefficients are obtained. Good agreement is achieved, in some cases within experimental error margins, for properties where experimental data are known. A very low IR intensity for triplet ozone is predicted.
