A term analysis of the Fe III spectrum in the ultraviolet region enables the writers to predict Fe III lines which fall in the astronomically observable region. Several of them are present in B-type stars, both as absorption and as emission lines. [less ▲]

The exceptional intensity distribution of bands of unsymmetrical molecules like CN and CH in a comet spectra can be explained by taking into consideration the following factors: (a) the frequency of electronic absorption processes; (b) the distribution in the vibrational levels (ground state) which is a function of the nuclear temperature TI or of the equivalent radiation temperature Tλ; (c) the distribution in the rotational levels corresponding to the nuclear temperature. These factors are different functions of the heliocentric distance r. [less ▲]
