The collision energy values were chosen while keeping in mind the highest number of product ions registered without losing the [M+H] + or [M−H] − signals of ... WebSolution. Dissociation in chemistry is defined as the splitting of complex molecules, ionic species or compounds into simple ions, atom, or molecule. Degree of dissociation is defined as the fraction of solute ions ( carrying current) dissociate at specific given temperature.
