Factors of Frank Condon Blockade

  • Thread starter bekjunhao
  • Start date
In summary, the conversation discusses the factors that affect and cause Frank Condon blockade (FCB), which is the suppression of current flow due to the slow entry of molecules into a new vibrational level. The person is seeking help in understanding the factors that cause FCB, as explained in a paper they have read.

Homework Statement [/b]

Which are the factors that affects and causes frank condon blockade?

The attempt at a solution[/b]

First of all, i understand that FCB is the suppression of current flow due to the fact that your molecules can't enter the new vibrational level compatible with the nuclear positions and momenta of the vibrational level of the molecule in the originating electronic state AS FAST AS your electron jumping from the electrode to the molecule.

I tried reading the paper found here
http://arxiv.org/ftp/arxiv/papers/0812/0812.3826.pdf

But i really need some help with understanding the factors that are causing FCB in a general case, can't digest the paper after reading it.

Thank you guys so much~~

FAQ: Factors of Frank Condon Blockade

What is the Frank Condon Blockade?

The Frank Condon Blockade is a phenomenon in spectroscopy where the excitation of a molecule or atom to an excited state is blocked due to rapid relaxation back to the ground state.

What factors contribute to the Frank Condon Blockade?

The factors that contribute to the Frank Condon Blockade include the energy difference between the ground and excited state, the strength of the transition dipole moment, and the rate of relaxation back to the ground state.

How does the Frank Condon Blockade affect spectroscopy?

The Frank Condon Blockade can lead to a lack of absorption or emission peaks in spectra, making it difficult to accurately measure the energy levels of a molecule or atom.

Can the Frank Condon Blockade be overcome?

Yes, the Frank Condon Blockade can be overcome by adjusting the experimental conditions, such as changing the temperature or pressure, to alter the rate of relaxation and allow for the observation of absorption or emission peaks.

What applications does the Frank Condon Blockade have in science?

The Frank Condon Blockade has applications in fields such as spectroscopy, quantum mechanics, and photochemistry. It can also be used to study molecular dynamics and energy transfer processes in molecules and atoms.
