The B3LYP/4-31G approach is used to compute the harmonic frequencies o
f substituted naphthalenes and their cations. The substitution include
s hydroxyl (OH), formyl (HC = O), and methylol (-CH2OH), at both the 1
and 2 sites. Also studied is 2-oxonaphthalene (= O). The TR spectra o
f these substituted species are compared with that of naphthalene. (C)
