J. 647, 1535-1542 (2006), DOI: 10.1086/505615
COMMENTS: The absorption spectra of NH3, NH2D, NHD2, and ND3 were measured using synchrotron radiation as a light source (spectral resolution 0.02 nm) and mixtures of NH3 and ND3, of which the equilibrium concentrations for all four isotopologues obey statistical distributions
