INFORMATION ACCESSIBLE THROUGH TDELFINFORMATION ACCESSIBLE THROUGH TDELF
How long does it take to break a bond ina laser field?
Which bond breaks first, which second, etc, in a collision process?
Are there intermediary (short-lived) bonds formed during a collision, which are not present any more in the collision products ?
