Abstract

Opto-acoustic high-resolution spectroscopy of the

v = 1 \to 2

vibrational-rotational transitions of the

{}^{2}Π_{\frac{1}{2}}

and

{}^{2}Π_{\frac{3}{2}}

states of NO is reported. Accurate frequencies for the 1→2 band centers for both the

{}^{2}Π_{\frac{1}{2}}

and

{}^{2}Π_{\frac{3}{2}}

states are obtained. The opto-acoustic detection technique has allowed Zeeman spectroscopy of the excited-state transitions.
