Abstract
Theoretical and experimental investigations of linewidth and lineshape of ro-vibrational lines of molecules in free jets show some very interesting features which are not observed in conventional infrared spectroscopy. This paper reports on recent data on NH3 obtained with semiconductor diode and colour center lasers and comments on the splitting of individual ro-vibrational lines, a feature observed by all investigators. It is proposed that a reliable explanation of the splitting can be obtained by considering the higher degree of condensation at the jet axis as compared with the radial direction, in accordance with the observed temperature and molecular density distribution in the jet.
