TLDR
In this article, an investigation of the absorption spectra of both 14NO2 and 15NO2 has revealed a long progression of red-degraded bands in the region 3 700 −4 600 A.Abstract:
An investigation of the absorption spectra of both 14NO2 and 15NO2 has revealed a long progression of red-degraded bands in the region 3 700–4 600 A. The rotational analysis shows that these bands ...read more

Triatomic Photofragment Spectra: I. Energy Partitioning in NO2 Photodissociation,
George E. Busch,Kent R. Wilson +1 more
TL;DR: In this paper, the photofragment spectrum of NO2 has been measured in the near ultraviolet at 28 810 cm−1 and at least two prominent peaks in the translational energy distribution were found to correspond to nearly equal probability of recoil with the NO fragment in the v=0 and v=1 vibrational states.

Triatomic Photofragment Spectra. II. Angular Distributions from NO2 Photodissociation
George E. Busch,Kent R. Wilson +1 more
TL;DR: The angular distribution of recoil of O atoms from the photodissociation of NO2 at 28 810 cm−1 was analyzed to obtain information about the lifetime and symmetry of the excited dissociative state.

Anomalously Long Radiative Lifetimes of Molecular Excited States
TL;DR: In this paper, four mechanisms which may account for anomalous radiative lifetimes in collision-free molecules are presented using the properties of the stationary states of the molecules, and the two mechanisms which are most important for polyatomic molecules lead to highly perturbed energy levels and correspondingly complex spectra.

The Electronic Absorption Spectra of NH$_{2}$ and ND$_{2}$
K. Dressler,D. A. Ramsay +1 more
TL;DR: In this article, a detailed analysis of the absorption spectra of a femtosecondron was carried out with a 21 ft. concave grating spectrograph, and it was shown that the spectrum consists of a long progression of the bending vibration in the excited state.

The magnetic rotation spectrum of singlet-triplet transitions
W.H Eberhardt,H. Renner +1 more
TL;DR: Magnetic rotation spectra have been found corresponding to the singlet-triplet transitions in formaldehyde, glyoxal, and benzoquinone as mentioned in this paper, but no magnetic rotation spectrum was found for transitions reported to be of this type in several other substances.
