        This laboratory was developed by undergraduate students in   collaboration with the course instructor as part of a   peer-developed and peer-led lab curriculum in a general chemistry   course. The goal was to explore the hypothesis that crystal   violet lactone was responsible for the thermochromic properties   of a sipping straw using a FT-IR for experimental determinations   of vibrational frequencies, UV–vis to quantify the color change,   and the software packages Spartan and Gaussian 09 for theoretical   calculations.
