Doppler-Limited Rotational Spectrum of the NH Radical in the 2 THz Region

Popis výsledku v původním jazyce

The Doppler-limited rotational spectrum of the NH radical in its electronic (X (3)Sigma(-)) and vibrational ground state has been measured using the frequency stabilized Cologne side-band spectrometer in the frequency region near 2 THz. The nitrogen N-14nuclear hyperfine patterns have been observed accompanying the resolved fine (J'' <-- J") structure of the N = 2 <-- 1 rotational transition. The observed peak frequencies were analyzed in detail together with the previously measured hyperfine frequencies of the N = 1 <-- 0 rotational transition and with combination differences obtained from the high-resolution electronic spectra to derive precise rotational, centrifugal distortion, fine, and hyperfine parameters. In the numerical analysis the essential attention has been paid to partly resolved and unresolved hyperfine structures. The peak positions of the partly or fully overlapped lines were analyzed with the help of a profile simulation.
