Finding a musical note to hertz converter is your easiest bet. They're quite easy to find on the interweb. A good start is that UV Westminster Chimes are in F major, which makes it extremely easy to figure out what the notes are.

If anyone could send me a recording of one, I can run it through an FFT and tell you the exact frequency.

The fundamental frequencies are as follows (and are in the order shown): 440 Hz, 349 Hz, 393 Hz, 262 Hz, Rest (no tone), 262 Hz, 393 Hz, 440 Hz, 349 Hz. There are also overtones present, but I don't believe you are interested in those. The touch tones preceding the chime appear to be 1###*5.

Sorry for being offtopic, but what is that program called?

The program I use is called "Smaart." The name is actually an acronym, and stands for "Sound Measurement Acoustical Analysis Real Time (tool)." But there are many similar (and cheaper) programs available. You just need something that performs an FFT (Fast Fourier Transform) on a mic input or a sound file. I like to study acoustics as a hobby, so Smaart has many features that I need, above and beyond the basic FFT.
