Again, thanks for going to the trouble to introduce some "heavy" ideas into the conversation about fading case colors. Very thought provoking, CZ.
I may lack understanding to the extent that I missed it, but did you address why the polymorphs that fade in color, always fade to a duller shade of the same color, but never change to a different color? They always fade into oblivion when continued abrasion enters the picture.
Regarding this statement, "I have done experiments where the end product slowly transformed into a different polymorph at room temp, in ambient light. We would Mass spec the compound as soon as created, and by an hour later, they reverted to another form." ...........Did you try the same experiment to see if it would transform so drastically in darkness? Wouldn't that be the only way to know that light was the "culprit"?
