能级

• These atoms have the simplest energy level schemes .
  这些原子的能级图最为简单。
• The spacing of translational energy levels is very small .
  平动的能级间隔极少。
• The b1 level will become empty .
  B1能级变成空域。
• For a harmonic oscillator the energy levels are evenly spaced .
  对谐振子来说，能级是等间隔的。
• Thus each orbit may be called, alternatively, an energy level .
  因此，每一个轨道也可以交替地称作一个能级。
• Such photons will excite the higher vibrational levels of the oh molecule .
  这种光子会激发OH分子的较高振动能级。
• Triatomic and larger molecules have more complex energy-level diagrams .
  三原子分子和更大的分子的能级图比较复杂。
• As the atoms approach, the splitting between the energy levels will be increased .
  随着原子的接近，能级之间的分裂将增加。
• This is why it is acceptable to speak of well-defined energy levels .
  这就是为什么我们还能接受所谓充分确定的能级这样的说法。
• Relativistic motion of the electron produces fine structure among the energy levels .
  电子的相对论性运动在能级中产生精细结构。
