Infrared and Raman Spectra of Solid Guanine Derivatives. 7-METHYLGUANINE, 9-METHYLGUANINE, 9-ETHYLGUANINE, 1,7-DIMETHYLGUANINE, and 1,9-DIMETHYLGUANINE.

Abstract

The infrared and Raman spectra of 7-methylguanine, 9-methylguanine, 9-ethylguanine, 1,7-dimethylguanine, and 1,9-dimethylguanine in the solid state have been reported and discussed. Hydrogen bonds in these solid guanine derivatives bring about strong perturbations which are discussed in terms of structural data given by X-ray diffraction methods. The spectra of guanine and 9-methylguanine are compared with the spectra of the monomers isolated in low-temperature matrices.

Key Words:
