Depends what level your analytical chemistry skills are :), some books will throw you straight into advanced quantum theory, save functions and making you derive schrodingers equation by yourself, weras others will explain the basic idea behind a mass spec / nmr spectrometer, so it is really dependant on what you want.
To be honest, the internet has ALOT of material on spectroscopy, I read a lot of chemistry literature on physical chemistry as its my favorite specialisation, but you can't quite get better than the internet, as it will have several different levels of explanantion.
Although a lot of people here may think the internet is a bit shakey, I am guessing that because your a 1st year you don't have a dire need for exremely specialised obscure peer reviewed papers on a certain aspect of wave particle duality, and most of the basics are generally uncontraversial enough for wiki to be basically right on.
