Reception in hBar at 3:30 pm

Most molecules even of modest size are nevertheless large enough that their potential energy surfaces support more than one minimum energy geometry; that is, the molecule can rearrange into unique structural or conformational isomers.  This talk will describe recent work in my research group using double or multi-resonant spectroscopy to record microwave, infrared, or ultraviolet spectra of single isomers in a mixture, free from interference from one another.  This opens up fascinating applications in peptide folding, combustion chemistry, and planetary atmospheres photochemistry.
