JET-COOLED FLUORESCENCE EXCITATION-SPECTRA AND CARBONYL WAGGING POTENTIAL-ENERGY FUNCTIONS OF SEVERAL CYCLIC-KETONES IN THEIR S1(N,PI-ASTERISK) ELECTRONIC EXCITED-STATES Academic Article uri icon

abstract

  • The jet-cooled fluorescence excitation spectra of the n* transitions of cyclopentanone, 3-cyclopenten-1-one, and cyclobutanone have been analyzed to determine the vibrational energy spacings in the S1(n, *) electronic excited states for the out-of-plane carbonyl wagging motions. A double-minimum potential energy function was determined for each and the barriers were found to be 680, 926, and 1940 cm-1, respectively. The carbonyl wagging angles were determined to be 22, 26, and 41, respectively. 1992.
