Abstract
UV-induced isomerization of monomeric glycine and 2-hydroxypyrimidine in Kr, Ar and Ne matrices was investigated using Fourier transform inf rared (FTIR) spectroscopy. The spectral bands of the three conformers of glycine and two tautomers of 2-hydroxypyrimidine were detected unam biguously. UV irradiation caused the partial conversion of the hydroxy form of 2-hydroxypyrimidine into the oxo form. The efficiency of the isomerization of glycine and 2-hydroxypyrimidine was reduced in the Ne matrix in comparison with the Ar and Kr matrices. (C) 1997 Elsevier S cience B.V.
