Abstract
The ultraviolet spectrum of the OH molecule has been obtained in electric fields up to 64 000 volts per cm. Stark line splittings, broadenings, and field-induced parity-forbidden transitions have been observed. The electric dipole moment of OH in its electronic and vibrational ground state (X2Π) has been determined to be (1.727 ± 0.02) Debyes. The dipole moment in the first excited vibrational state has been found to be about 4% lower.Keywords
