 Title: FTMW SPECTROSCOPY OF HSiCl Creators: Fukushima, Masaru; Jäger, Wolfgang Issue Date: 2001 Publisher: Ohio State University Abstract: We have observed HSiCl using the technique of Fourier transform microwave spectroscopy. HSiCl was produced in supersonic free expansions by pulsed discharge of $(CH_{3})_{3}SiCl$. The lowest frequency rotational transition, $1_{01} - 0_{00}$, was measured and the hyperfine structures due to the nuclear spins of $^{35}Cl$ and $^{37}Cl$ were analyzed. The obtained rotational constants, $\frac{1}{2}(B+C)$, were compared with those obtained by LIF optical $spectroscopy^{c}$. Using the nuclear electric quadrupole and nuclear spin-rotation coupling constants obtained, the electronic structure of HSiCl was investigated.
