标题[问题] 统计热力学两题
时间Tue Dec 29 13:29:47 2009
最近在看统计热力学，作者是JOHN F. LEE FRANCIS W. SEARS
看到第五章量子力学部分，课文看完，但是作後面的习题有些还是不太会作，
因此想请问板上高手帮忙解惑一下，我的问题点是不太了题目最後要求的是甚麽？
感激不尽。
问题一.
It is observed that light emitted from a vibrating hydrogen molecule has
a wavelength of 2.270*10^-6m .Assuming that this radiation comes from
transitions between adjacent excited states of a one-dimensional harmonic
oscillator (with △E = hc/λ,where λ is the wavelength of the observed
radiation),what is the value of the equivalent spring constant for a hydrogen
molecule?
问题二.
It is observed that light emitted from a rotating oxygen molecule must come
from adjacent rotational states,i.e.△j=1. Determine the frequencies of the
four lowest transitions if I=1.94*10^39gm cm^2.
