SUMMARY

The discussion centers on the compound corrections needed for Stopping and Range of Ions in Matter (SRIM) simulations. It is established that chemical bonds can be approximated by treating the material as a sum of carbon and hydrogen, leading to compound corrections that vary between 2-20% based on the specific molecule. The user suggests researching toluene and longer-chain hydrocarbons for more precise data, although significant differences are not anticipated.

PREREQUISITES
  • Understanding of SRIM software and its applications.
  • Basic knowledge of chemical bonding and molecular structure.
  • Familiarity with hydrocarbons and their properties.
  • Experience with interpreting simulation data and results.
NEXT STEPS
  • Research the impact of chemical bonds on SRIM results.
  • Investigate the properties and corrections for toluene in SRIM.
  • Examine the effects of longer-chain hydrocarbons on ion stopping power.
  • Learn about the methodologies for calculating compound corrections in SRIM.
USEFUL FOR

Researchers and scientists working in materials science, particularly those utilizing SRIM for ion interaction simulations, as well as chemists focusing on molecular properties and corrections in computational models.

TL;DR
I need a to get the peak energy deposited by muons in polyvinyl toluene [CH2CH(C6H4CH3)]n for a scale calibration. I think I can do this via the stopping power but cannot find bragg/compound correction online. Anyone know of a way to determine it from the chemical fomula?

To a good approximation, you can ignore chemical bonds and just treat it like the sum of carbon and hydrogen in the material.

Thats what it does by default, the compound correction is due to the bonds. I found sources saying it causes a variation of 2-20% depending on the molecule.
 
You can see if you find numbers for toluene or some hydrocarbons with a longer chain. I don't expect large differences however.
