For the first time, the hyperfine structure of the rotational J = 1 - 0 (K=0) and J = 2 - 1 (K=0,1) transitions of phosphine has been resolved by using microwave spectroscopy. To this purpose, the Lamb-dip technique has been employed. In addition, the J = 3 - 2 (K=0,1,2) transition has been recorded at Doppler resolution. The present investigation allowed us to provide accurate values for most of the hyperfine constants as well as ground state rotational parameters.

Abstract
For the first time, the hyperfine structure of the rotational J = 1 - 0 (K=0) and J = 2 - 1 (K=0,1) transitions of phosphine has been resolved by using microwave spectroscopy. To this purpose, the Lamb-dip technique has been employed. In addition, the J = 3 - 2 (K=0,1,2) transition has been recorded at Doppler resolution. The present investigation allowed us to provide accurate values for most of the hyperfine constants as well as ground state rotational parameters.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
