Interparticle Distance Vector Formula:
From: | To: |
Definition: The interparticle distance vector is the mean distance vector between microscopic particles (usually atoms or molecules) during collision dynamics.
Purpose: This calculation helps in understanding and predicting molecular collision outcomes in chemical reaction dynamics.
The calculator uses the formula:
Where:
Explanation: The formula calculates the effective distance between particles considering their collision energy, approach distance, and rotational energy effects.
Details: Accurate distance calculation is crucial for predicting reaction probabilities, scattering angles, and energy transfer in molecular collisions.
Tips: Enter the total collision energy in Joules, miss distance in meters, and centrifugal energy in Joules. All values must be > 0.
Q1: What is miss distance (b)?
A: Miss distance is how close particles approach each other when there's no force acting between them.
Q2: How is centrifugal energy determined?
A: Centrifugal energy is related to particle motion on a circular path and depends on angular momentum and reduced mass.
Q3: What factors affect the interparticle distance?
A: Collision energy, particle masses, impact parameter, and potential energy surfaces all influence the distance.
Q4: Can this be used for all types of molecular collisions?
A: This formula works best for simple two-body collisions with central forces.
Q5: What units should I use?
A: Use consistent SI units - Joules for energy and meters for distance.
