Dear CCL= ers,

I am so= rry for resending me request! I was so distracted that did not read my mess= age!
I think no one will understand my message!
Here is the correct question:

<= span style=3D"font-family: 'times new roman', 'new york', times, serif;">I = am looking for a practical solution for measuring the binding energy of a&n= bsp;
charged complex in uniform electric field. As far as I know this is = not a 
trivial task!
For neutral or charged systems without electr= ic field one can employ the following 
equation for measuring the binding ne= rgy:

E(binding)[AB+]=3D E[AB+] - {EA + E[B+]}

However, for charged systems in= external field the total energy is a gauge 
dependent property. Doe= s anyone know an example in literature that someone 
measured the binding energy = of charged species in electric filed? 
Any help will be highly appre= ciated. 

With my sincere regards,
Cina Foroutan-Nejad

Dear CCLe= rs,

I am looking for a practical solution for measuring the binding = energy of a
charged complex in uniform electric field. As far as I know= this is not a
trivial task!
For neutral systems without electric fi= eld one can employ the following
equation for a charged complex:

E(binding)= [AB+]=3D E[AB+] - {EA + E[B+]}

However, for charged systems in exter= nal field the total energy is a gauge
dependent property. Does anyone k= now an example in literature that someone
measured the binding energy o= f charged species in electric filed?
Any help will be highly appreciate= d.

With my sincere regards,
Cina Foroutan-Nejad
