Psychologists have found that twins, in their early years,
tend to have lower intel- ligence and pick up languages more slowly
than nontwins. The slower intellectual growth of twins may be
caused by benign parental neglect. Suppose we want to investigate
this phe- nomenon. A random sample of 50 sets...

The fundamental vibrational transition of the 12C16O in the
electronic ground state from v=0 to v=1 occurs at 2,170 cm-1. The
bottom of the Morse potential for the anharmonic oscillator is well
approximated by a parabola, the potential well for the harmonic
oscillator, especially when the transition is measured with
precision limited to 1 cm-1. a) Demonstrate that, in the harmonic
oscillator approximation of the IR spectroscopy, the frequency of
the fundamental transition is equal to the frequency of the...
