Studies on long-lived states and coherences in NMR (original) (raw)

2PL 1 40 + Years of NMR : Now and Then

2005

In this lecture, I will recall the developments of NMR over the past 50 years, as perceived through the eyes of a romantic “nomad” who happened to have wandered into the field by random walk some 40 years ago. Even at age 50 plus, NMR continues to amaze me as a vibrant intellectual discipline with many exciting possibilities for applications across a broad front of science. The power and limitation of NMR for some of these applications will be highlighted and discussed.

P A R T I FUNDAMENTALS AND TECHNIQUES PRINCIPLES IN NMR SPECTROSCOPY

More than any other analytical method the nuclear magnetic resonance (NMR) spectroscopy provides information about the chemical structure and the dynamics of organic 3 molecules. The interpretation of the NMR data depends on a minimum amount of basic information that will be provided in this chapter. For a better appliance, these basics of oneand two-dimensional NMR techniques are demonstrated by means of practical examples. 0 2 J ° = 8.5 Hz J ° = 11.5 Hz J ° = 14.5 Hz J 180 = 15.5 Hz J 180 = 12.5 Hz J 180 = 9.5 Hz 4

Ampere NMR School 2008 Abstracts

2008

It is my great pleasure to welcome you to the next AMPERE NMR SCHOOL in Poland, which takes place in Poznań and Wierzba (The Great Mazurian Lakes). The School will give you the opportunity to expand your knowledge, to share new ideas with the colleagues from all over the world, to contribute to your scientific development and at the same time to get to know Polish culture and nature. I hope you will enjoy your stay in Poland and bring home unforgettable memories.

Modern NMR spectroscopy of proteins and peptides in solution and its relevance to drug design

The knowledge of the three-dimensional (3D) structures and conformational dynamics of proteins and peptides is important for the understanding of biochemical and genetic data derived for these molecules. This understanding can ultimately be of help in drug design. We describe here the role of Nuclear Magnetic Resonance (NMR) spectroscopy in this process for three distinct situations: for small proteins, where relatively simple NMR methods can be used for fhll 3D structure determination; for larger proteins that require multinuclear multidimensional NMR but for which full 3D structures can still be obtained; and for small peptides that are studied in interaction with macromolecules (receptors) using specialized NMR techniques. A fourth situation, pertaining to large systems where only partial structural information can be obtained from NMR data, is briefly discussed. Molecules of interest to the biomedical field (C5a and stromelysin) are discussed as examples.

Essential Terminology Connects NMR and qNMR Spectroscopy to Its Theoretical Foundation

ChemRxiv, 2021

Classical 1D 1H NMR spectra are prototypic for NMR spectroscopy in that they represent a wealth of chemical information encoded into convoluted graphs or patterns that contain complex features (aka multiplets), even for seemingly simple molecules. Accordingly, the utility of NMR depends on the theoretical and visual skills required to extract all the physical parameters that represent usable structural and quantitative information. Moreover, it depends on the ability of the analyst to communicate them effectively and reproducibly. After decades of continuous development, NMR spectroscopy has reached a stage where its analytical capabilities have outgrown the typical level of detail of interpretation, especially of 1D NMR spectra. The quantum-mechanical (QM) foundation, history, evolution, and (in-)consistency of widely applied terminology calls for re-examination and recalibration. In order to develop new perspectives on solution-state NMR analysis, including the rapidly evolving qu...

Theory and Applications of NMR to Problems in Material

2010

The path to my Ph.D. has been long and challenging, and I have been extremely fortunate to get constant support from a lot of people. First and foremost, I would like to thank Prof. Leonard J. Muller (Len to most of us) for his valuable mentorship and constant guidance. I still remember talking to him over the phone from India, when I was trying to make a choice on graduate schools (3:00 am India time!). His genuineness was apparent even over a long distance phone call. He has been a great friend throughout my six years of graduate school, being a mentor when necessary and a loving friend at all other times. He is a very intelligent and careful scientist who has taught me the value of sincerity, honesty, critical thinking, persistence, and hard work. We have shared a lot of life experiences, lunches and coffees together, especially in the final few years of my graduate education. Wherever I go in the future, I will miss him and his warm demeanor! vi I would like to thank my committee members, Prof. Christopher Bardeen and Prof. Jingsong Zhang, for their constant support during my graduate studies at UCR. They have guided me and helped me get through the program, by sharing their experiences and scientific knowledge.
