Observation of the (A)over-tilde-(X)over-tilde electronic transition of the CF3O2 radical
The first observation of a sharp, structured electronic spectrum for a fluorinated alkyl peroxy radical is reported using the technique of cavity ringdown spectroscopy (CRDS). The Tao value for the (A) over tilde (2)A' -(X) over tilde (2)A " transition of CF3O2 has been determined to be 6656(3) cm(-1) values for (A) over tilde state vibrational frequencies have also been determined. Initial kinetic observations on CF3O2 have been carried out, using CRDS to monitor its concentration.
