A study of the excited states of 1,3,5-heatriene was conducted using the CIS/6-31+G(d) method. The excitation energy for the most intense transition (oscillator strength = 1.69) was computed to be 5.67 eV. Determine the absorption wavelength for the transition (that is, calculate where this excitation energy would appear on a UV-Vis spectrum). Report your result in units of nm.
