One class of such compounds are derivatives of 4-hydroxycoumarin (4HC), some of which show significant water solubility. The 4HC family of compounds have a strong absorption feature in the UVB, making them susceptible to photolysis by sunlight. The Feierabend group has set out to study the kinetics and mechanism of the photochemistry of aqueous-phase 4HC compounds, with a particular focus on warfarin, the most prevalent 4HC rodenticide, as well as a commonly prescribed pharmaceutical for blood-clotting. This lecture will present the story of their photochemical fate as studied using chemical kinetics, absorption and emission spectroscopy, computational chemistry, and mass spectrometry, the work for which was a focus for Dr. Feierabend\u2019s recent research leave. Results suggest that warfarin may degrade significantly over short time periods in surface waters with the formation of toxic byproducts.<\/p>\n\n\n<div  class=\"tribe-events-schedule tribe-clearfix\" >\n\t<p class=\"tribe-events-schedule__datetime\">\n\t\t<span class=\"tribe-events-schedule__date tribe-events-schedule__date--start\">\n\t\t\tJanuary 28, 2025\t\t<\/span>\n\n\t\t\t\t\t<span class=\"tribe-events-schedule__separator tribe-events-schedule__separator--date\">\n\t\t\t\t@\t\t\t<\/span>\n\t\t\t<span class=\"tribe-events-schedule__time tribe-events-schedule__time--start\">\n\t\t\t\t11:00 am\t\t\t<\/span>\n\t\t\n\t\t\t\t\t\t\t\t\t<span class=\"tribe-events-schedule__separator tribe-events-schedule__separator--time\">\n\t\t\t\t\t&#8211;\t\t\t\t<\/span>\n\t\t\t\n\t\t\t\t\t\t\t<span class=\"tribe-events-schedule__time tribe-events-schedule__time--end\">\n\t\t\t\t\t11:50 am\t\t\t\t<\/span>\n\t\t\t\n\t\t\t\t\t\t\t<span class=\"tribe-events-schedule__timezone\">EST<\/span>\n\t\t\t\t\t\t<\/p>\n<\/div>\n\n\n\n<p>Ruth W.
