High resolution infrared spectra have been measured for mixtures of 1,1,1,2-tetrafluoroethane in Ne, expanded in a supersonic planar jet. The m 14 fundamental is an essentially unperturbed C-type band, exhibiting many DK c ¼ AE2 transitions. Accurate excited state rotational and distortion constants
## Abstract A novel technique is described for measuring the site selectivity of methods for labelling the major CFC‐alternative, 1,1,1,2‐tetrafluoroethane (HFA 134a), with fluorine‐18 (__t__~1/2~ = 109.7 min). The carbon–carbon bond in radiofluorinated HFA 134a is broken in the ion source of an is
## Abstract A report is given on the ionization/dissociation behavior of the title compounds within air plasmas produced by electrical corona discharges at atmospheric pressure: both positive and negative ions were investigated at different temperatures using atmospheric pressure chemical ionizatio
