The 2v2,v1andv3bands of H216O

Abstract
The 2v 2, v 1 and v 3 bands of H2 16O occurring in the region 2930–4255 cm-1 were studied from a spectrum recorded with a high resolution Fourier transform spectrometer (resolution: 0·005 cm-1). The set of the observed transitions leads by a least squares method to the determination of very accurate values of the rotational levels belonging to the vibrational states (000), (020), (100), (001). From these levels, using Watson's Hamiltonian, we have obtained respectively 21 and 17 rotational constants for the states (000) and (020).
