This paper describes the spectroscopy of Na3F both in the frequency and time domains.
The photoionization efficiency curve shows two thresholds, associated to two isomers. The excited electronic states of the C
isomer have been probed by photodepletion spectroscopy, and the
results are used to analyze a time-resolved study of photoexcited Na3F, probed by photoionization. The pump-probe signal clearly shows damped oscillations, the period of which is fitted to 
fs, close to twice the previously measured bending mode of Na2F [1], while the relaxation time is 
fs.
