Electric Dipole Moment of the n—π* Singlet State of HCOF

Abstract
Stark‐effect measurements of the 2480 Å band of formyl fluoride have been made. The dipole components are μa′=+1.65±0.1 D and |μb|=2.0(+0.5 or −1.0) D. The sign of μa′ is the same as that of μa″, in disagreement with a picture of excitation localized in the carbonyl group.
