Anomalous stark effects in the millimetre wave spectrum of formyl fluoride

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

Measurements of Stark effects in the rotational spectra of formyl andd-formyl fluoride show the presence of anomalous components that vary in strength with the field. They occur predominantly at high fields and may possibly be a molecular polarisability effect. In addition the normal molecular dipole moment is found to be (1.99±0.03)D, oriented almost parallel to the C-H bond and at an angle of 79° to the C-F bond. This is discussed in connection with the molecular structure.

Riassunto

La misura dell’effetto Stark nello spettro rotazionale del fluoruro di formile ha mostrato la presenza di componenti anomale che cambiano di intensità con il campo. Esse si presentano a campi elevati e possono essere dovute ad un effetto di polarizzazione molecolare. È stato determinato il momento dipolare normale il cui valore è (1.99±0.03)D; esso è orientato quasi parallelamente al legame C-H e fa un angolo di 79° con il legame C-F. Questi dati sperimentali vengono discussi in connessione con la struttura molecolare.
