Problem
An organic dye in solution exhibits a strong absorption line at a frequency of 5.80×1014Hz. Answer the following questions. (Use the fundamental constants provided on the AP Chemistry reference sheet; report all answers with appropriate units.)
(1) Calculate the wavelength of the absorbed photon.
(2) Determine the type of molecular transition (rotational, vibrational, or electronic) most likely responsible for this absorption.
(3) Explain, in the context of molecular structure, why the identified transition type is consistent with the observed frequency.
