The Water-Vapor nu(2) Band Lineshift Coefficients Induced by Nitrogen Pressure.
The water-vapor lineshift coefficients in the nu(2) band induced by nitrogen pressure were measured with a FT spectrometer of Paris University at the spectral resolution of 0.005 cm(-1) for the line with angular moment of upper states up to 16. Calculations were made using Anderson formulation of semiclassical impact theory. The calculated lineshifts agree satisfactorily with measured values, but for some lines, deviations were found. The analysis revealed the systematic J trend in subbranches, which consists of transitions with the same values of quantum number K(a) and equally changing K(a) and K(c).
