The buffer-gas pressure broadening coefficients and the temperature dependent parameter of the third overtone band of NO at 1.35-1.38 mu m by N-2 and rare gases for two ground electronic states, (2)Pi(1/2) and (2)Pi(3/2), were investigated for rotational levels of P(7.5)-R(14.5) using continuous-wave cavity ring-down spectroscopy. Obtained pressure-broadening coefficients are consistent with literature values.
