Abstract

Raman spectroscopy is still a suitable and prominent method for probing the relationship between structure, dynamics and function of biomolecules. In this context, resonance Raman spectroscopy is of particular relevance since it allows the site‐specific investigation of chromophores (aromatic amino acid residues, nucleotides, heme groups) which are directly involved in mechanisms pivotal for the function of the respective molecules. Time‐resolved spectroscopy (Raman and IR) is utilized to explore, e.g., structural changes in heme proteins upon ligand photolysis. Conventional visible Raman is still a useful tool to explore peptides and proteins and to determine the orientation of oriented nucleic acid fibres. Copyright © 2005 John Wiley & Sons, Ltd.

## Abstract Raman spectroscopy was used to study the liquid–solid water phase transition. Special attention was devoted to the OHstretching band of the Raman spectrum, which shows monotonous changes in the temperature range between 10 and − 15 °C. The interpretation of this spectral change, as wel

The microwave spectra of N(2)-O(3) and N(2)-SO(2) have been recorded in the 6-18 GHz range using a pulsed-nozzle, Fourier transform microwave spectrometer. C-type transitions have been observed for both complexes which are slightly shifted by internal tunneling motions of the O(3) or SO(2) moieties.
