Millimeter 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 کاملFT-MWAND MILLIMETER WAVE SPECTROSCOPY OF PANHs: PHENANTHRIDINE, ACRIDINE, AND 1,10-PHENANTHROLINE
The pure rotational spectra of phenanthridine, acridine, and 1,10-phenanthroline, small polycyclic aromatic nitrogen heterocycle molecules (PANHs), have been measured and assigned from 2 to 85 GHz. An initial spectral assignment, guided by ab initio molecular orbital predictions, employed broadband Stark modulated millimeter wave absorption spectroscopy of a supersonic rotationally cold molecul...
متن کاملGround State Centrifugal Distortion Constants of Trans-Acrolein, CH2 = CH—CHO from the Microwave and Millimeter Wave Rotational Spectra
The pure rotational spectrum of trans-acrolein in the ground vibrational state has been assigned in the frequency region from 8 GHz to 180 GHz. The measured absorption lines encompass a-type transitions from the " R k , q Q i . qQs branches and 6-type transitions from the r P 0 , r P x , r P 2 , rR0 brandies for values of J up to 23. The rotational constants have been refined and all quartic an...
متن کاملMicrowave spectrum and structure of the dimethylamine dimer: Evidence for a cyclic structure
Rotational spectra have been measured for six isotopomers of the dimethylamine dimer using a Fourier-transform microwave spectrometer. No tunneling splittings were observed for either the aor c-type rotational transitions and the spectra could be fit to a rigid rotor Hamiltonian including centrifugal distortion terms. Possible dimer structures are discussed and compared to the experimentally de...
متن کاملSuperconducting Microstrip-Fed Antenna Coupled to a Microwave Kinetic Inductance Detector
A proper antenna to couple to a microstrip Microwave Kinetic Inductance Detector (MKID) is designed and simulated. A twin-slot microstrip-fed inline antenna is designed for frequency band of 600-720~GHz integrated with an elliptical lens and coupled to the MKID. A systematic design procedure for design of such antenna with microstrip inline feeding is presented. Whole structure of lens and twin...
