Abstract
In this talk we report our study of $^{12}C_{2}H_{4}$ monomer and its clusters in $^{4}He$ with the new, ""second generation"" helium droplet/infrared spectroscopy apparatus at UNC. The region containing the $\nu_{11}$ and $\nu_{9}$ asymmetric C-H stretches of the monomer was scanned using a tunable, cw OPO aligned collinearly with the droplet beam and detected with a quadrupole mass spectrometer. Rotationally resolved spectra were observed with line widths as narrow as $0.08 cm^{-1}$, FWHM. Details of the new instrument and the analysis of the spectra will be presented.
