✦ Synopsis

The rotational spectra of the unstable HCCCP molecule have been investigated in the millimeter-wave region for the main excited vibrational states which lie below 1000 cm Ϫ1 , namely 4 (COC stretch), 5 (HCC bend), 6 (CCC bend), 7 (CCP bend), 2 6 , 2 7 , 3 7 , 4 7 , 5 ϩ 7 , and 6 ϩ 7 . l-type resonance effects have been taken into account in the analysis of the spectra, so that the values of the anharmonicity constants x L(66) , x L(77) , x L(57) , and x L( 67) could be determined. The anharmonic interactions which couple the 4 state with 6 ϩ 7 , 2 6 , and 4 7 have been also considered, yielding the unperturbed value of the ␣ 4 vibration-rotation coupling constant.

We have measured millimeter-wave transitions of PO, produced by the chemiluminescent reaction of oxygen with white phosphorus, P 4 , in excited vibrational states up to v = 7. We were hence able to obtain more precise rotational, spin-rotation, -doubling, and hyperfine constants for this radical and
