A review is presented of experimental studies of infrared and Raman spectra of thymine isolated in an argon matrix at about 12 K. The experimental techniques for study of the vibrational spectra of matrix-isolated pyrimidines are described, and the r

One-to-one complexes of ammonia with the neutral transition metals, Cu and Fe, have been formed in solid argon matrices at 12 K and investigated spectroscopically in the infrared region. FTIR spectra reveal large shifts in the ν 2 NH 3 umbrella mode

The IR absorption spectra in the NH, OH and SH stretching regions of 2-thiouracil and its N 1 -, N 3 -, O - and S -alkyl derivatives, isolated in the vapour phase and also isolated in inert low temperature matrices, and the UV absorption spectra of t

The infrared spectrum of 9-methylguanine isolated in an argon matrix at 15 K, and the effect of ultraviolet irradiation on this spectrum, are presented and discussed. These studies prove that the amino-oxo and amino-hydroxy tautomers of 9-methylguani

The change in tautomeric equilibria of purine and pyrimidine bases which may occur as a result of changes from an inert to polar environment of the base is examined in a general way. The contributions to the interaction energy between two molecules o

A variety of N-(dialkylaminomethyl)benzotriazoles are shown by 1H and 13C n.m.r., i.r., and X-ray crystallography to exist solely in the 1-substituted form in the crystalline phase, but as an equilibrium mixture of the 1- and 2-isomers in the liquid,
