- The infrared spectra of the four isomers of the C5H10O molecule are given below. Match the spectra with the compounds whose structures are given.Elements can be identified by their visible spectra. Could analogous techniques be used to identify compounds from their molecular spectra? In what region of the electromagnetic spectrum would the appropriate radiation lie?7. Consider the Jablonski diagrams below, where So, S₁, and S2 are all singlet electronic states, and T₁ is a triplet electronic state. (So is the electronic ground state.) The horizontal lines indicate the vibrational energy levels in each electronic state. The arrow drawn on the diagram represents the absorption of a UV photon with = 250 nm, promoting the molecule to a high vibrational level in the S₁ state. (The wavelength values here and below are meant as a guide, but this is not really a quantitative question.) Two different processes are described below the diagrams. Read each one, and then draw an appropriate set of arrows on the corresponding diagram to represent the process described.

- The “signature” infrared absorption that indicates the presence of a C-H stretching motion in a molecule occurs at wavelengths near 3.4 × 10-6m. Use this information to estimate the force constant of the C-H stretch.Take the reduced mass in this motion to be approximately equal to the mass of the hydrogen atom (a good approximation when the H atom is attached to a heavy atom).Q.1: The force constant of the bond in HCl is (516 N/m). Assuming the value of the force constant does not depend on the mass of the atoms in the molecule, calculate the fundamental vibrational frequency of each of the following: 'HCl. 'H'Cl and ?H*Cl.
