1. The fundamental vibration of 1H19F is at 3961.64 cm-1. Using the harmonic oscillator model, calculate the “force constant” of the bond (in N/m) and use this value to predict the fundamental frequency of both 2H19F and 1H18F in wavenumbers. Briefly explain why the fundamental frequencies are so different. (amu masses: 1H = 1.0078, 2H = 2.0140, 18F=18.0009, 19F=18.9984) 2. What is the fundamental frequency of the vibrational mode best described by the term “symmetric stretch”?
