E-CAM Physical Constant module¶
Purpose of Module¶
This module enables to use fundamental physical constants (speed of light in vacuum, Planck constant … and isotopic masses). Two versions can be selected:
- The CODATA 2006 ones, downloaded from NIST and the NIST masses downloaded in 2012 (default).
- Constants and masses from the 70th edition of the Handbook of Chemistry and Physics.
From these fundamental constants, some conversion factors are calculated automatically and can be used easily.
Remark: the actual mass values of the NIST web page differ slightly from the module ones.
Background Information¶
This module has been extracted and modified from the ElVibRot-Tnum-Tnum code (ElVibRot_f90-v80.13-Tnum28.9-Tana5.1). This pre-E-CAM version can be downloaded here.
Installing¶
Dependencies: this module needs the fortran modules in the Source_Lib/sub_system directory.
Build the module (with dependencies):
make PhysConst
Build the module documentation (with doxygen):
make doxy
Testing¶
Two example data/script files:
Examples/exa_PhysicalConstants/dat_PhysConst
Examples/exa_PhysicalConstants/dat_PhysConst_HandBook70ed
To test the installation, you can run both test examples.
cd Examples/exa_PhysicalConstants ; ./run_tests
The results will be compared to previous results in Examples/exa_PhysicalConstants/output_17dec2016 file.
Source Code¶
The source code can be downloaded from the E-CAM GitLab service.
