Data frame/Dataset summarizing the essential characteristics of nuclei in EPR spectroscopy.
Format
A data frame with 351 rows and 9 variables/columns:
- No_Proton
Numeric, proton number.
- Isotope
Character, ponting to isotope in format like "14N".
- Stability
Character, pointing either to stable, "STB", or radio-active, "RA", isotope.
- Name
Character, corresponding to isotope name.
- Spin
Numeric, denoting the spin quantum number.
- g_Nuclear
Numeric, corresponding to nuclear \(g\)-factor (\(g_{\text{n}}^{}\)).
- Abund_Natur_Percent
Numeric, pointing to natural abundance of an isotope in \(\%\).
- Q_Barn
Numeric, corresponding to nuclear quadrupolar moment in \(10^{-28}\,\text{m}^2\).
- nu_ENDOR_MHz_035T
Numeric, specific Larmor/ENDOR frequency (\(\nu_{\text{ENDOR}}^{}\)) at \(0.35\,\text{T}\).
Details
This dataset was taken form `EasySpin` toolbox
and only it's format was slightly modified. Therefore, IT CONTAINS THE ENTIRE INFORMATION
LIKE THE ORIGINAL DATASET (see the Source). For better orientation in ENDOR spectra,
column with the Larmor/ENDOR frequencies (in MHz) at 0.35 T was added according to =>
$$\nu_{\text{ENDOR}}^{} = - (1/h)\,\mu_{\text{N}}^{}\,g_{\text{n}}^{}\,B\,10^{-6}$$
where \(h\) is the Planck's constant, \(\mu_{\text{N}}^{}\) is the nuclear magneton
available from constants
package (constants::syms$mun,syms), \(g_{\text{n}}^{}\)
is the nuclear \(g\)-factor of the specific nucleus (reported in the data frame as g_Nuclear)
and finally, the \(B = 0.35\,\text{T}\) denotes the magnetic flux density. The negative sign "\(-\)" mirrors
convention to describe the direction of magnetic spin moments precession (see also eval_nu_ENDOR) either
counter-clockwise (\(+\), if \(\gamma_{\text{n}}^{} < 0\)) or clockwise (\(-\), if \(\gamma_{\text{n}}^{} > 0\))
Please, consult the vignette("datasets") as well.
