Structures of Cage, Prism, and Book Isomers of Water Hexamer from Broadband Rotational Spectroscopy
TLDR
It is reported that broadband rotational spectroscopy in a pulsed supersonic expansion unambiguously identifies all three isomers of the water hexamer; their oxygen framework structures are determined by means of oxygen-18–substituted water (H218O). Expand
A broadband Fourier transform microwave spectrometer based on chirped pulse excitation.
TLDR
The CP-FTMW spectrometer produces an equal sensitivity spectrum with a factor of 40 reduction in measurement time and a reduction in sample consumption by a factors of 20, and displays good intensity accuracy for both sample number density and rotational transition moment. Expand
DETECTION OF E-CYANOMETHANIMINE TOWARD SAGITTARIUS B2(N) IN THE GREEN BANK TELESCOPE PRIMOS SURVEY
The detection of E-cyanomethanimine (E-HNCHCN) toward Sagittarius B2(N) is made by comparing the publicly available Green Bank Telescope (GBT) PRIMOS survey spectra to laboratory rotational spectraExpand
Laboratory and tentative interstellar detection of trans-methyl formate using the publicly available Green Bank Telescope PRIMOS survey
The rotational spectrum of the higher-energy trans conformational isomer of methyl formate has been assigned for the first time using several pulsed-jet Fourier transform microwave spectrometers inExpand
THE DETECTION OF INTERSTELLAR ETHANIMINE (CH3CHNH) FROM OBSERVATIONS TAKEN DURING THE GBT PRIMOS SURVEY
We have performed reaction product screening measurements using broadband rotational spectroscopy to identify rotational transition matches between laboratory spectra and the Green Bank TelescopeExpand
INTRAMOLECULAR DYNAMICS FROM EIGENSTATE-RESOLVED INFRARED SPECTRA
Understanding intramolecular energy flow in molecules is one of the central goals of chemical physics. Statistical theories [such as Rice-Ram­ sperger-Ka:;sel-Marcus (RRKM) theory] of unimolecularExpand
The rotational spectrum of epifluorohydrin measured by chirped-pulse Fourier transform microwave spectroscopy
Abstract The rotational spectrum of epifluorohydrin measured by chirped-pulse Fourier transform microwave (CP-FTMW) spectroscopy is presented. A new CP-FTMW spectrometer capable of measuring theExpand
Vibrational dynamics of carboxylic acid dimers in gas and dilute solution.
TLDR
The gas phase dynamics of hydrogen-bonded cyclic dimers of trifluoroacetic acid and formic acid are insensitive to both the specific excitation energy and the chemical identity of the dimer. Expand
Distinguishing tunneling pathways for two chiral conformer pairs of 1,3-propanediol from the microwave spectrum.
TLDR
The microwave spectrum of the sugar alcohol 1,3-propanediol has been measured over the frequency range 6.7 to 25.4 GHz using both cavity and broadband microwave spectrometers and accurate dipole moment components have been obtained from Stark effect measurements for the lowest-energy form. Expand
Microwave spectrum of 1,2-propanediol
Abstract The microwave spectrum of the sugar alcohol 1,2-propanediol (CH3CHOHCH2OH) has been measured over the frequency range 6.5–25.0 GHz with several pulsed-beam Fourier-transform microwaveExpand
