Dear friends,

How does the example of chem4 distinguish background radical H3O plus or OH minus produced by ionized water from H3O plus or OH minus produced by reactions of other radicals?

Best wishes.

Dear,

in chem4, the simulation is limited up to 1 us then background radical H3O plus and OH minus for example at pH 7 don’t impact to water radiolysis at 1 us. If you want to do the simulation at lower or higher pH. You can try chem6 (but you will need to re-computer reaction rate of reaction type 6 to your pH) or UHDR with your pH.
