Chemists use infrаred аbsоrptiоn spectrа tо identify the chemicals in a sample. In one sample, a chemist finds that light of wavelength 6.0 microns is absorbed when a molecule makes a transition from its ground harmonic oscillator level to its first excited level. Find the energy of this electron [energy] in eV. If the molecule has mass 5.7 x 10-26 kg, find the force constant [constant] in N/m.
