Abstract:

The rotation-inversion spectrum of ¹⁵NH₃ has been recorded between 38 and 280 cm^?1 with a resolution of about 0.03 cm^?1. By combining the present results with the inversion frequencies obtained by microwave spectroscopy, the following main rotational and centrifugal distortion constants were derived (in cm^?1):

State	$B$	$D_{J}$	$D_{JK}$
$v_{inv} = 0$	9.92235	0.0008493	?0.001575
$v_{inv} = 1$	9.91742	0.0008336	?0.001532
