TLDR
In this paper, the Raman spectrum of the 1-methyl-uracil single crystal was recorded in order to determine the symmetry of the different vibrational modes, and the internal (molecular) spectrum was assigned in accordance with the in-plane and out-of-plane character of the vibrations served, and at the same time, the previously calculated vibrational frequencies were assigned.About:

Infrared matrix isolation spectra of 1-methyluracil: Revised assignment based on the Hartree–Fock and post-Hartree–Fock studies
TL;DR: In this article, a revised assignment of the infrared spectra of monomeric 1-methyluracil isolated in Ar and N2 matrices is presented, based on the Hartree-Fock and second order Moller-Plesset perturbation (MP2) methods using the D95V** basis set.

Low‐frequency Raman spectra of guanosine and nucleotides in ordered states: Origin of the lowest‐frequency mode
TL;DR: In this paper, the origin of the lowest Raman active mode of deoxyribonucleic nucleic acid (DNA) is attributed to the motion of bases stacked in a column.
