The first-order Raman spectrum of diamond has been measured in a diamond anvil cell up to 27 GPa. The fundamental phonon line varies linearly in pressure with a shift of 2.87 cm-1/GPa. This line appears to be an excellent pressure-calibration standard as an alternate to the ruby pressure scale.

This is what we did; this is what we got; this is what it’s good for. Three sentences. Efficient scientific writing at its best.
I signed off on a paper I’m et al. on, and finished and sent off my review today, in addition to the usual lab grind. And I didn’t even cite-nap the authors. It has been a good day.
