Given experimental and observed values, how can I do minimized chi square fitting in order to obtain the best fit in MATLAB?

01 January 2017 0 438 Report

Hello,

I am trying to calculate rotational and vibrational temperature using the spectrum fitting method in plasma. Please see the attached figure for N2 0-0 band. The simulated spectrum has been plotted along with the experimental one (unresolved spectrum). Now, I want to do Chi square fitting of the simulated spectrum with the experimental one. Many articles mention the fitting methodology is done after this step but I am stuck in this step in this step.

Can somebody help me in doing chi square fitting using MATLAB when the intensities for simulated and experimental data at a particular wavelength are known ?

I am eagerly looking for your kind reply...

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...
