In the phrase:

> 先生が立ち去ると...

why would you choose to use 立ち去る rather than just 去る? Is there a possible
ambiguity from using just 去る? Does it have a different nuance?

Implication of 立ち去る versus 去る
* 立ち去る is to _walk_ away on foot from some place. If you get on a car or train immediately after saying goodbye to someone, that's not 立ち去る.
  * 去る has a broader sense, "to leave" in general. Depending on the context, it can mean something very strong, for example, quitting a company forever, parting with someone forever.

立ち去る and 去る are probably interchangeable in your case, but when you describe
something that can happen everyday, 立ち去る would sound a bit safer.

answer
According to the dictionary, 立ち去る means to actually get up and leave a place:  
たちさる【立（ち）去る】立ってその場所から去る  
<http://dictionary.goo.ne.jp/jn/136997/meaning/m0u/%E7%AB%8B%E3%81%A1%E5%8E%BB%E3%82%8B/>

So the meaning is slightly different than just 去る (to leave).
