Analysis of IR spectra of carbon clusters trapped in noble gas matrices using algorithms based on digital filtering techniques.
IR spectra of carbon clusters C(n) (n>/=3) trapped in noble gas matrices (Ar and Kr) at temperatures of 13, 30 and 35 K are analyzed using algorithms based on digital filtering techniques and non-linear least-squares fitting. The spectral features at different temperatures and in different matrices are discussed. The majority of the resolved lines are assigned to C(n) cluster species based on data obtained via quantum chemical computations and from tunable laser IR spectrometry of C(n) species in the gas phase. A complete analysis of the IR spectra is available upon request.
