Rotational spectrum in the v6=1 and v3=1 levels of chloroform

Altogether there have been measured almost 800 rotational transitions in the v6=1 vibrational state and more than 250 transitions in the v3=1 vibrational state. These have been reproduced quantitatively with standard deviations of 43 and 32 kHz in the v6=1 and v3=1 levels, respectively, leading to considerable improvement of determination of molecular constants of the studied levels.
