The NMR razors are simple and (probably) powerful applications that can simulate a spectrum directly from the molecular formula. For the user's point of view it works like a (very) simplified version of ChemDraw. When you have finished drawing the structure, you hit a button to simulate the spectrum. When you hit the button, the program asks you such spectroscopic details like solvent, temperature, magnetic field, etc.. When you have finished this further step, the razor calls home. Yes, because all you have downloaded is a graphic interface, the true program is running into a remote and ultra-secret location.
I like this program because I have understood everything in 5 minutes.
To start with, I have simulated the 1-H spectrum of ethyl acetate in CDCl3, at 200 MHz.
Here it is:
Well, you know, I am not a lucky guy! Enough for today. If you want to try by yourself:

This morning I shaved my face with a Gillette blue II. It is as good as a Gillette can be and it is much cheaper than the other models of the same brand. Officially it is disposable, yet I don't remember when I bought it. Quite likely I have been using the same razor for 3 or 4 months. As long as it works... Two complete reviews in a single post, I am very productive...
