Self-broadening and self-shift in the $3{\nu }_2$ band of ammonia from mid-infrared-frequency-comb spectroscopy

Guang Yang, Vinicius Silva de Oliveira, Dominic Laumer +4

We report the broadband absorption spectrum of the $3{\nu }_2$ band of ${}^{14}$NH${}_3$ near 4 $\mu m$. The data were recorded using a mid-infrared frequency comb coupled to a homebuilt F…
