Extended Analysis of the K = 3 Inversion-Rotation Doublets for 14ND3 and 15ND3 in the v2 = 1 Excited State

Abstract

Several K = 3 doublets of 14ND3 and 15ND3 in the v2 = 1 excited vibrational state have been observed. With the new lines we were able to obtain improved values for the [FORMULA OMITTED] and [FORMULA OMITTED] constants. For 14ND3 [FORMULA OMITTED] = 2.3517(15) · 10−5 MHz, [FORMULA OMITTED] = − 1.068(8) · 10−8 MHz, and for 15ND3 [FORMULA OMITTED] = 2.3548(23) · 10−5 MHz, [FORMULA OMITTED] = 1.061(10) · 10−8 MHz. © 1987, Walter de Gruyter.
