The Laboratory Millimeter-wave Spectrum of Methyl Formate in Its Ground Torsional E State
Over 250 rotational transitions of the internal rotor methyl formate (HCOOCH3 ) in its ground ( V1 = 0) degenerate (E) torsional substate have been measured in the millimeter-wave spectral region. These data and a number of E-state lines identified by several other workers have been analyzed using an extension of the classical principal-axis method in the high barrier limit. The resulting rotat...
متن کاملMillimeter Wave Rotational Spectrum and Centrifugal Distortion
Intensive studies have been carried out on the rotational spectra of various isotopic species of ketene, H2C = C = 0 , since 1950 [ 1 6 ] . The centrifugal distortion analysis of ketene [3, 4 ] , together with information from additional infrared data [3, 5 ] , enabled Mallinson and Nemes [6] to reevaluate the molecular force field for ketene. Recently, microwave investigations on the higher ho...
متن کاملMillimeter-Wave Spectrum of the NO Dimer
The pure rotational spectrum of the NO dimer, (14N16O)2, has been studied in the 225-400 GHz millimeter-wave region by means of direct absorption in a supersonic jet expansion. Previously, only 4 rotational transitions of (NO)2 had been measured in the microwave region. To these, we have added 66 new millimeter-wave transitions with values of J ranging from 4 to 16 and of Ka from 2 to 7. Most t...
متن کاملGallium Phosphide IMPATT Sources for Millimeter-Wave Applications
The potentiality of millimter-wave (mm-wave) double-drift region (DDR) impact avalanche transit time (IMPATT) diodes based on a wide bandgap (WBG) semiconductor material, Gallium Phosphide (GaP) has been explored in this paper. A non-sinusoidal voltage excited (NSVE) large-signal simulation method has been used to study the DC and high frequency characteristics of DDR GaP IMPATTs dsigned to ope...
متن کاملA millimeter-wave redshift search for the unlensed HyLIRG, HS1700.850.1
We report the redshift of an unlensed, highly obscured submillimetre galaxy (SMG), HS1700.850.1, the brightest SMG (S850μm=19.1 mJy) detected in the JCMT/SCUBA-2 Baryonic Structure Survey, based on the detection of its CO line emission. Using the IRAM PdBI-WIDEX with 3.6 GHz band width, we serendipitously detect an emission line at 150.6 GHz. From a search over 14.5 GHz in the 3-mm and 2-mm atm...
