The BLYP/6-31G and BP/86 (and probably the pBP/DN ) correction factors are very close to unity. For the frequencies of polycyclic aromatic hydrocarbons calculated by the B3LYP/6-31G method, Bauschlicher multiplied frequencies below 1300cm by 0.980 and frequencies above this by 0.967 [58]. In their paper introducing the modification of Becke s hybrid functional to give the B3LYP functional, Stephens et al. studied the IR and CD spectra of 4-methyl-2-oxetanone and recommended the B3LYP/6-31G as an excellent and cost-effective way to calculate these spectra [49]. With six different functional. Brown et al. obtained an agreement with experimental fundamentals of ca. 4-6%, except for BHLYP [77].
