Line strengths and self-broadening of pure rotational lines of nitrous oxide measured by terahertz time-domain spectroscopy

Pure rotational lines of nitrous oxide were observed using terahertz time-domain spectroscopy. Measurements were carried out at pressures of 0.7–1.2 bar. Line intensities and self-broadening parameters of transitions from J'′=10←9 to J′=53←52 were measured directly for the first time. Good agreement with the HITRAN database was found.
