Abstract
Rotational spectra of various isotopomers of the NeArHCl trimer, including those with $H^{35}Cl, H^{37}Cl, D^{35}Cl, D^{37}Cl, ^{20}Ne$, and $^{22}Ne$ were studied with a pulsed jet cavity Fourier transform microwave spectrometer. Both a- and b-type transitions could be measured in the frequency range from 3.8 to 17 GHz. Nuclear hyperfine structures due to $^{35}Cl, ^{37}Cl$, and D were observed and analyzed. The resulting spectroscopic constants were used to derive effective structural parameters. The possibility to gain insight into non-additive contributions to the interaction energy through comparison with NcHCl, ArHCl, and $Ar_{2}HCl$ is discussed.
