Water hexamer We have recently published a paper in Science (vol. 336, p. 897) regarding the determination of the structures for three isomers of the water hexamer. Although population analysis suggests all three are closely spaced in energy, additional experiments have determined the cage as the global minimum for the hexamer in a supersonic expansion.
CP-FTmmW Spectrometer A new paper in JMS (doi: j.jms.2012.07.015) describes our new CP-FTmmW spectrometer, capable of acquiring broadband spectra from 260-290 GHz at room temperature. Recent developments in detection and waveform generation technology has enabled video-rate, real-time spectral acquisition and coherent averaging.
E-cyanomethanimine detection in Sgr B2(N) A new paper in Astrophys. J. Lett. (Vol 765, p. L10) describes our new detection of the prebiotic molecule E-cyanomethanimine, suggested to be an important precursor of adenine, using the freely available GBT PRIMOS survey data.
