Normal modes analyses for different molecules with biological interest have been performed and checked via the calculation of resonance Raman intensities. For this purpose, molecular orbital calculations were used to determine bond order changes in t

It has very recently been reported that deoxyribonucleic acid oligomers of cytosine with sequences such as d-T(CN)T aggregate into tetrastranded sructures [J. L. Leroy et al. (1993), Biochemistry, Vol. 32, pp. 6019–6031; K. Gehring et al. (1993), N

In order to answer the question of what the structure of DNA is in the nucleus of a living cell where its long length must be subjected to repeated folds in order to pack it into such a small space, a laser Raman microscope was designed and built to

A remarkably high viscosity has been induced in protein aqueous solutions by the addition of certain structurally related organic solvents. The effect has been observed for lysozyme aqueous solutions containing tetramethylurea (TMU), dimethylsulfoxid

An equation been derived to calculate, ab initio, the frequencies and intensities of a resonant Raman spectrum from the transform theory of resonance Raman scattering. This equation has been used to calculate the intensities of the ultraviolet resona

Resonance Raman spectra have been obtained with 218-nm excitation for Escherichia coli and Staphylococcus epidermidis. Large intensity differences seen in the tryptophan-associated 1556-cm−1 peak appear to be strongly related to Gram type. Unlike E

A general valence force field for 1-methylthymine (1MeT) in the isolated state has been unequivocally determined from the calculation of both the frequencies and the relative ultraviolet resonance Raman intensities arising from the first lowest lying
