Research output: Contribution to journalArticle


A tunable diode laser spectrometer was used to perform measurements of absolute line intensities for 20 transitions in the ν-fundamental of propyne centered at 15.5 μm. From these data, the vibrational band-strength S was significantly determined to be S = 196.8 ± 6.0 cm atm at 297 K. These results will be used for further applications of astrophysical interest such as a refined contribution for modelling Titan's atmosphere.
