Abstract

The visible dye laser spectroscopy of molecules such as CuOH made in a Broida-type oven is discussed. CuOH is made by the reaction of Cu vapor with H₂O₂. We believe we have discovered at least three new electronic states in CuOH. After that Fourier transform spectroscopy of transient molecules found in both laboratory and extraterrestrial sources is described. Using the 4-m telescope at Kitt Peak we have discovered the infrared absorption spectra of C₃ and C₅ in the envelope of the carbon star IRC + 10216. The Fourier transform spectrometer at the McMath Solar Observatory was used to record the spectra of CH₃N and CCN radicals. An Engelking-type of free jet expansion source provided ultracold electronic emission spectra.
