Calculation of \(g\)-factor according to fundamental formula (see Value).
  The magnetic flux density (B.val) and microwave frequency (nu.val,\(\nu\))
  can be defined, having the common units like G (Gauss) mT
  (millitesla) or T (tesla) as well as GHz or Hz.
Value
\(g\)-Value from \((\nu h)/(\mu_{\text{B}} B)\). Physical constants (\(\mu_{\text{B}}\)
  and \(h\)) are taken from constants
  package by the syms.
