The laser used was a Nd:Yag with a 5 ns pulse width operated at the fundamental wavelength (1064 nm) and the doubled and tripled wavelengths (532 nm and 355 nm). Butane (/ ˈ b juː t eɪ n /) or n-butane is an alkane with the formula C 4 H 10.Butane is a gas at room temperature and atmospheric pressure. Butane is an important industrial chemical in which photo-processes are very important for the initiation of reactions.

Chem. 6 �`�p This MassBank Record with Accession JP009304 contains the MS mass spectrum of 'BUTANE (D10)'. The mass spectra of each isomer of the butane molecule display a very weak molecular ion and are dominated by fragment ion peaks. Relative photoionization cross‐section curves have been determined for parent and fragment ions of ethane, propane, and n‐butane over the photon‐energy range from the ionization potential to 14.0 eV. Mass spectral interpretation is the method employed to identify the chemical formula, characteristic fragment patterns and possible fragment ions from the mass spectra.

Recent advances in nanosecond pulsed laser technology have led to high laser intensities being available to researchers to enable these photo-processes to be studied in compounds such as butane.
