We report here the vibrational analysis and lifetime measurement by laser induced fluorescence spectroscopy of the $\tilde{A} {^{3}E} \leftrightarrow\tilde{X} {^{3}A_{2}}$ system of $CH_{3}N$. Following vibrational frequencies of the $\tilde{A}{^{3}E}$ state were determined: $\nu_{1}=2943 cm^{-1},\nu_{2}=1239 cm^{-1}, \nu_{3}=759 cm^{-1},\nu_{5}=1500 cm^{-1}, and \nu_{6}=728 cm^{-1}$ The lifetime of the $\tilde{A} {^{3}E}$ state at four vibrational states with $\nu_{3}=0, 3, 4,$ and 6 were measured to be $299 \pm 5, 201\pm 7, 198\pm 12$, and $183\pm 8$ ns, respectively. Our experiments show that the $\tilde{A}{^{3}E}$ is bound at least up to $4800 cm^{-1}$ above the zero point energy, and is relatively free from the photochemistry. en_US dc.format.extent 46001 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title INVESTIGATION OF THE $\tilde{A} {^{3}E} \leftrightarrow\tilde{X} {^{3}A_{2}}$ SYSTEM OF THE METHYLNITRENE RADICAL BY LASER SPECTROSCOPY en_US dc.type article en_US
