Discussion Overview

The discussion revolves around the behavior of excited electrons in relation to photon absorption, specifically why an excited electron does not absorb an additional photon before returning to the ground state. The scope includes conceptual understanding and experimental evidence regarding multiphoton absorption.

Discussion Character

  • Conceptual clarification, Debate/contested, Experimental/applied

Main Points Raised

  • One participant questions why an excited electron does not absorb an extra photon before transitioning to the ground state.
  • Another participant challenges this assumption, suggesting that it is possible for excited electrons to absorb more energy.
  • A later reply confirms that multiphoton absorption is indeed possible and has been demonstrated experimentally.

Areas of Agreement / Disagreement

There appears to be disagreement regarding the initial assumption that excited electrons cannot absorb additional photons, with some participants asserting that multiphoton absorption is a valid phenomenon.

Contextual Notes

The discussion does not resolve the underlying assumptions about photon absorption and the conditions under which multiphoton absorption occurs.

please tell me that why is it that an excited electron don't absorbs an extra photon before coming to ground state.

What makes you think that it doesn't?

okkkkkkkay i got the idea so excited electron can absorb more energy.

You are making very little sense here.

Multiphoton absorption is certainly possible and has been shown experimentally[1]. This is not new.

okay thanx:smile:
