New Interpretation

The photoelectron spectrum of NO (Turner and May 1966) is given a new interpretation in terms of electronic states of NO+ belonging to configurations … (5σ)2(1π)32π and … 5σ(1π)42π. The close analogy with corresponding states of N2 and CO is pointed out. The long-known β Rydberg series of absorption bands of NO is shown to converge towards … 5σ(1π)42π, 3Π, but no evidence can be found for the existence of an electronic state of NO+ at the limit of the α series. The previously assumed Rydberg character of this series appears to be erroneous.

Annealing Experiments

The 1.945eV band is the dominant end product of annealing radiation damage in diamonds containing isolated substitutional nitrogen atoms. In this paper uniaxial stress experiments are described which show the band to be a transition between A 1 (ground) and E (excited) electronic states of a trigonal centre, the E state being coupled predominantly to A 1 modes of vibration. Annealing experiments suggest that the centre is either a substitutional nitrogen atom plus an interstitial nitrogen atom, or a substitutional nitrogen atom plus a vacancy. Small differences between the luminescence and absorption bands are shown to be consistent with the double minima vibrational potential of the nitrogenvacancy model.
