Williams, Darren L.; Flaherty, Thomas J.; Alnasleh, Bassam K. – Journal of Chemical Education, 2009
A concise roadmap for using computational chemistry programs (i.e., Gaussian 03W) to predict the color of a molecular species is presented. A color-predicting spreadsheet is available with the online material that uses transition wavelengths and peak-shape parameters to predict the visible absorbance spectrum, transmittance spectrum, chromaticity…

Nicholson, Barbara J.; Halkin, Sylvia L. – Bioscene: Journal of College Biology Teaching, 2007
A laboratory exercise is presented in which students determine where metabolic heat is primarily generated in blooming eastern skunk cabbage ("Symplocarpus foetidus") plants. Students consider how color, shape, and orientation of spathes, and stage of flower maturation, may affect metabolic heat production and retention of both metabolic and solar…
