Reports on the fluorescence excitation spectrum of the argon-hydrogen carbon oxygen (Ar-HCO) van der Waals molecules. Detection of at least eight bands associated with the complex; Spectral shift of the lowest energy band from the origin of free HCO transition; Average separations in both electronic states; Decay lifetime of the strongest Ar-HCO band.
