Unfortunately, unless you can get ahold of an older, unmarked copy, you may be disappointed by the "new" book sold through Amazon. Spectra are cut off, along with the legends. The pages look like they were photocopied, poorly, in some cases and the text on several pages is blackened by photocopied handwriting within the book. Strange, as Dover is typically very conscientious. I found another older copy and must say, I really do enjoy this book. It reads well and Herzberg describes many aspects of atomic spectroscopy and how structure is related quite brilliantly. I can highly recommend the book, but not this particular printing.
