description

Abstract The linear Stark effect in the ν 3 fundamental of 28 SiF 4 has been investigated with IR-IR double resonance employing CO 2 laser sidebands at microwave modulation frequencies. The frequencies needed for the double-resonance experiment were generated from one laser line by a novel double-modulation technique. As a result, the parameter of the vibration-induced dipole moment was determined to μ 33 = −0.10288(56) D. For the centrifugal distortion moment in the ν 3 excited state the value μ 0 = 6.06(36) × 10 −7 D was found. From the Stark splitting in the vibrational ground state, μ 0 = 6.81(10) × 10 −7 was determined.
