N° 106. — Observation et analyse vibrationnelle d’un nouveau système de bandes du monochlorure de germanium : A²Σ⁺ —X²Π

Rotationally Resolved LIF Spectra of the A2Σ+–X2Πr Transition of Jet-Cooled 74Ge35Cl

“…In an attempt to increase the magnitude of the observed fluorescence signals, a variety of germanium-containing precursors were employed in our discharge jet experiments. When GeCl 4 was used, we observed several vibrational bands of the previously identified A 2 + -X 2 r transition of germanium monochloride (4)(5)(6). A literature search showed that six electronic transitions have been observed for GeCl, although the A-X band system has never been rotationally analyzed.…”

“…Deschamps et al (4) and Babu et al (5) reported conflicting assignments in the late 1960s and then, almost 20 years later, Balfour and Chandrasekhar (6) (B & C) reanalyzed the emission spectrum, using the observed germanium and chlorine isotope effects to verify their assignments. In the present work, we have been able to obtain jet-cooled laser induced fluorescence (LIF) spectra of the A 2 + -X 2 1/2 system of GeCl for the first time.…”

Microwave spectrum of the GeCl radical

“…The electronic spectrum of GeCl has been observed by several authors in the ultraviolet [6][7][8][9][10][11][12] and visible regions [13][14][15]. The resonance enhanced multiphoton ionization (REMPI) spectroscopy was also reported [16].…”
