Hi Leandro, I would not expect E0 to vary with temperature between 10 K and 300K. Just to be sure nothing untoward happened, I would recommend taking a spectrum at 300 K at the end of the series as well as at the beginning. That's generally a good policy with a series like that just to make sure the sample didn't suffer an irreversible change from oxidation, condensation, beam damage, or whatever. --Scott Calvin Sarah Lawrence College At 09:44 PM 2/25/2007, you wrote:
But coming back to the original question, would you say that analyzing a temperature-dependent set of the very same NC-containing sample (eight measurements between 10K and 300K) to get an E0 value would be a sound approach? Or should we expect E0 to vary with the temperature as well?
