英文摘要: We report the cation spectra of the cis and trans rotamers of m-fluoroanisole, recorded by using the two-color resonant two-photon mass-analyzed threshold ionization spectroscopic technique. The adiabatic ionization energies of the cis and trans rotamers are 67 867 +/- 5 and 68 304 +/- 5 cm(-1), respectively. The observed active vibrations 6b, 6a, 1, and 12 are found to have frequencies of 473, 549, 714, and 955 cm(-1) for the cis rotamer and 463, 565, 714, and 962 cm(-1) for the trans rotamer of m-fluoroanisole in the cationic ground state, respectively. These results show that the frequency depends on the nature, vibrational pattern, relative orientation and the extent of the F and OCH3 substituents participation in the normal vibration.
