Abstract

New experimental measurements of the frequency separations of 30 pairs of

{}^{12}C

{}^{16}O_{2}

laser lines in the 10.4-μm band and 26 pairs in the 9.4-μm band have been made with Lamb-dip—stabilized lasers. The use of a Josephson junction as the frequency-mixing element simplified the measurements. Uncertainties in existing rotational constants for the laser vibrational levels were reduced 20 to 30 times and an additional rotational constant

H_{v}

was determined for the first time.
