摘要: The alkyl and aromatic CH stretch infrared spectra of inden-2-ylmethyl (I2M, C10H9) trihydronaphthyl (THN, C10H11) radicals have been recorded under jet-cooled conditions in the ground (D0) first electronically excited (D1) states using resonant ion-dip (RIDIR) spectroscopy. Previously, vibronic spectroscopy a series C10H9 C10H11 hydronaphthyl were investigated their thermochemical properties evaluated with isomer specificity [J. A. Sebree et al., J. Phys. Chem. A 11, 6255–6262 (2010)]. We show here that one m/z 129 spectral carriers characterized work was misidentified as 2-hydronaphthyl (2-HN) radical, appearing discharge 1,2-dihydronaphthalene close proximity to 1-hydronaphthyl radical. D0-RIDIR spectrum region positively identifies I2M, whose two-color two-photon ionization (2C-R2PI) recently reported by Schmidt co-workers [T. P. Troy Sci....
