Notes. The rms error of residuals are 2 kHz and 0.00004 cm-1 for the submillimetre-wave and far infrared lines, respectively. In parentheses, standard deviations of the molecular constants are given in units of the last digit.
Fixed at the value reported for 14NH multiplied by the 15N/14N nuclear magnetogyric ratio (−1.4028, see discussion section).
Fixed at the value obtained by scaling that reported for C(14NH) using the rotational constants and the ratio of the nuclear g values.
