On the electronic spectrum of formyl fluoride

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

The vapour spectrum of formyl fluoride in the range (2200÷2700) å shows about 60 non-diffuse bands. The comparison with the solution spectrum and the temperature effect allow to isolate two main progressions of the excited state, with a pass of about 1100 and 640 cm−1, assigned respectively to the carbonyl stretching and to the FCO deformation modes. The transition is probably of the singlet-singlet n-π type, with the origin at 37500 cm−1.

Riassunto

Lo spettro in vapore del fluoruro di formile nell’intervallo (2200÷2700) A consiste di circa 60 bande non diffuse. Il confronte con lo spettro in soluzione e l’effetto della temperatura consentono di isolare due progressioni principali dello stato eccitato, con passo di circa 1100 e 460 cm−1, assegnate rispettivamente al modo d’allungamento carbonilico ed a quello di deformazione FCO. La transizione è probabilmente del tipo singoletto-singoletton-π, con origine a 37500 cm−1.
