The ν2 band of 15NH3

Abstract High-resolution Fourier transform sepctra of the ν 2 band of 15 NH 3 have been recorded in the region 725–1250 cm −1 with a precision better than 0.0003 cm −1 . A simultaneous weighted least-squares analysis of these data, together with previously published data, has been carried out, to yield molecular parameters which fit the data within the limits of their experimental accuracies.
