The other day I was reading a book “Experimental Pulse NMR: A Nuts and Bolt Approach” by Eiichi Fukushima and Stephen B W Roeder and I was encountered with a sentence which says,”Fluorescent lights generate noise which can be picked up in the spectrometer.” (para 1, page 13). I wonder if they are talking about NMR spectrometer (as they don’t mention it explicitly in the sentence). I have never come across this statement anywhere and I liked it. I wonder what kind of frequency is emitted by fluorescence lamps other than visible spectrum which adds to noise in the spectrometer. May be thats the reason why NMR and fluorescence spectroscopists don’t get along with each other so nicely….:).

By the way the book mentioned above is really nice and I liked going through it.
