Extended Analysis of the K = 3 Inversion-Rotation Doublets for 14ND3 and ,15ND3 in the ν2 = 1 Excited State

Abstract

Several K = 3 doublets of 14ND3 and 15ND3 in the ν2 = 1 excited vibrational state have been observed. With the new lines we were able to obtain improved values for the η30 and η3J constants. For 14ND3 η30 = 2.3517(15) · 10-5 MHz, η3J= -1.068(8) ·10-8 MHz, and for 15ND3 η30 = 2.3548(23) · 10-5 MHz, η3J = 1.061(10)· 10-8 MHz.
