TD-ELF Examples

Ethyne (acetylene) in a strong laser field

TD-ELF ExamplesScattering of an energetic proton from ethene (ethylene)

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 ?
