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.

Calculated Temperature Dependence

The temperature dependence of emission from iodine, heated in a shock wave to 1000 K–2000 K, has been measured at 4550, 5550, 6950, 7550, and 7820 Å. Preliminary measurements of the emission at 6380 Å were also made. The temperature dependence of the emission was calculated at these wavelengths for transitions to the ground electronic state X(1Σg+) of iodine from the excited electronic states, A(3Π1u), (1Π1u), and [Formula: see text]. The calculated results are in a reasonable agreement with experimental data. For the banded emission due to the B → X transition, a theory of the temperature dependence of emission was developed. At 6950, 7550, and 7820 Å, the results of this theory agree with the experimental data thus identifying the B → X transition as the source of emission at these wavelengths. The temperature dependence of emission at 4550 Å is consistent with calculated temperature dependence for either (1Π1u) → X or [Formula: see text] transitions. The temperature dependence of the emission at 5550 Å is consistent with calculated temperature dependence for the above two transitions, as well as for the A(3Π1u) → X transition.

Excited Electronic States

Relative rates of reaction of a number of olefins with the ground state triplet and the first excited electronic state (the lowest singlet) of methylene have been determined at room temperature. The rates depend relatively little on olefin structure. Triplet methylene is somewhat more discriminating and, in particular, reacts considerably more rapidly with 1,3-butadiene than with monoolefins.

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.
