The i.r. spectral studies ofcytosine and its d,-deuterated derivative isolated in Ar and Ne matrices are reported. The amino-hydroxy and the amino-ox0 tautomeric forms dominate in matrices. Separation of the i.r. spectra of the two tautomers was based on observation of spectral changes following U.V

Using the proposed gas-phase structures of the dimer of carbon monoxide as guides, ab initio molecular orbital calculations have been carried out on this species in order to determine its probable structure in cryogenic matrices, and the vibrational spectrum of that preferred structure. The Fourier
The IR spectra of uracil and thymine predicted theoretically at the ab initio Hartree-Fock level with 6-31G\*\* basis set are reported and compared with Ar matrix experimental spectra. The IR spectra computed at the SCF/6-31G\*\* level reproduce the experimental spectra with an accuracy which allows
