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”?

What is the approximate wavenumber in cm-1 of the fundamental absorption due to the stretching vibration of a C≡N group? Assume the force constant for a triple bond to be about 1.53×103 N/m.
If a wind instrument, such as a tuba, has a fundamental frequency of 54.0 Hz, what are its first three overtones (in Hz)? It is closed at one end. (The overtones of a real tuba are more complex than this example, because it is a tapered tube.) first overtone _________Hz second overtone _________Hz third overtone ____________Hz
QUESTION9 2Marks) The fundamental mode of vibration (first harmonic) of a support cable in a suspension bridg may be used to determine the tension in the cable. An engineer measures the fundamental frequency and her calculations show the design specs for the mast. By what fraction will the tension in the cable change if the frequency was made 4% higher? that the frequency should be 4% higher in order to meet
