“…In the spectrum of pyridine N-oxide, this small band is hidden under a very strong S 0 → S 2 band. 51,52 Consistent with a similar interpretation for the absorption spectrum of 14 is the appearance of the TD-DFT S 0 → S 2 band at 412 nm, with an oscillator strength 105 times greater than that of the S 0 → S 1 band.…”

“…The original onset assignment was as an nπ * excitation; 12 however, Bist et al, 16,17 who identified all the fundamental modes, showed that the rotational band structure was only compatible with a ππ * ( 1 B 2 ) transition, which was confirmed by Nakagawa et al 13 from jet cooled spectra. Our spectrum (Fig.…”

“…Subsequently, Bist and Parihar 16,17 performed an analysis of the vibrational structure and identified all 30 fundamentals. Our long wavelength spectral limit is 29 214 cm −1 (3.622 eV); hence the 0-0 band (29 299 cm −1 , 3.633 eV) 13,16 of the lowest UV transition for PyNO was not observed in our study. A comparison of these previously reported electronic transition results with our low energy range (Fig.…”

“…The electronic structures and spectra of heterocyclic amine Noxides have been extensively studied by many researchers. [16][17][18][19][20][21] In the case of pyridine N-oxide, the strong π → π* band was observed near 280 nm, in aprotic solvents. This band has 1 A 1 symmetry and it has the largest contribution of the intramolecular charge transfer configuration due to the electron transition from the N-oxide oxygen atom to the ring π-system.…”
