It has a role as a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. hyb) and Evergreen (R. laciniatus L.) blackberries by dynamic headspace/OSME technique, J.

Agric. Maeda & Schatz (1961), among others, have noted that IR absorbance can vary non-linearly with ice thickness in reflection measurements, meaning that our A′ might not be applicable to other laboratory systems, much less astronomical observations.
