 Title: THE MICROWAVE SPECTRUM OF THE METHYLCYCLOPROPANE-HCl COMPLEX Creators: Forest, Susan E.; Andrews, Anne M.; Kuczkowski, R. L. Issue Date: 1993 Publisher: Ohio State University Abstract: The microwave spectrum of the methylcyclopropane(MCP)-HCl complex has been observed using a pulsed nozzle, molecular beam Fourier transform microwave spectrometer. Transitions were assigned with the aid of the quadrupole hyperfine structure from the chlorine nucleus. The rotational constants of the $C_{4}H_{7}-H^{35}Cl$ species are $A = 6408.1(2) MHz, B = 1410.486(1) MHz, C = 1224.155(1) MHz$. In addition to this species, the spectra of the MCP $H^{37}Cl$ and $MCP-DCl$ isotopomers have also been studied. The data is consistent with the HCl attached to the C-C bond of the MCP ring that is adjacent to the methyl substituted carbon.
