Another important instrument we got was a nuclear magnetic resonance. My students, in later years, looked at me when I said we got one of the first nuclear magnetic resonance spectrometers in the country. And the fact was that, except at a research level, this was Nobel laureate winning work that got the infrared spectra [sic - should be nuclear magnetic resonance] effect. And then of course people like Rex Richards took it up in this country and made great advances. But, in fact, it was quite late in time that NMR became available commercially, because we couldn’t make the instrument as a scientific piece of research – we weren’t competent to do that – but we needed a machine that worked. And, as you will know, as the years went by, it went from MHz to 40 to 60 to 100, 200, 500 and I don’t know what the limit is now, but it’s very high I’m quite sure. That was increase in technology, but we got one of the early ones, I think it was a 40 MHz, to start with.
