Abstract

Abstract Seven b-type P and R branch rotational transitions and seven a-type Q branch transitions have been measured for the slightly asymmetric rotor H 14N 3 in the microwave and millimeter wave regions. The information obtained from these transitions includes the rotational constant A 0 = 610996.2 (6.0) MHz, the component of the dipole moment along the b-axis |μ b | = 1.48 (5) debye, refined values of the rotational constants B 0 and C 0, and of the centrifugal distortion constants for this molecule. Combining the value of |μ b | with the value of |μ a | = 0.837 debye measured previously for K = 1 transitions the total dipole moment is found to be 1.70 (5) debye.
