Summary
The three rotational and six distortion constants of both formyl and d-formyl fluoride have been determined from their millimetre wave absorption spectra, using an improved method of calculation of centrifugal effects. The rotational constants are: for HCOF,A=91 156.56 MHz,B=11 760.23 MHz,C=10 396.72 MHz; for DCOF,A=65 096.59 MHz,B=11 761.74 MHz,C=9 941.71 MHz. Taken with electron diffraction data these yield the parametersr CH=(1.087±0.01) Å,r CO=(1.182±0.003) Å,r CF=(1.341±0.003) Å, andβ FCO=(123.04±0.02)°. Comparisons are made with the structure of the formyl grouping in similar molecules.
Riassunto
Sono state determinate le tre costanti rotazionali e le sei costanti di distorsione centrifuga del fluoruro di formile e del deutero fluoruro di formile studiandone gli spettri di assorbimento nella regione millimetrica e usando un metodo perfezionato di calcolo degli effetti centrifughi. Le costanti rotazionali sono: per HCOF,A=91 156.56 MHz,B=11 760.23 MHz,C=10 396.72 MHz; per DCOF,A=65 096.59 MHz,B=11 761.74 MHz,C=9 941.71 MHz. Tenendo conto dei dati di diffrazione elettronica, queste costanti rotazionali forniscono i seguenti valori per i parametri molecolari:r CH=1.087±0.01) Å,r CO=(1.182±0.003) Å,r CF=(1.341±0.003) Å eβ FCO=(123.04±0.02)°.
