Formula:
CaCO3
Formula with fragments:
CaCO3+6H2O
Formula with parentheses:
HO ((CH2)2O)6 H
Formula with isotope:
CaCO[18]3+6H2O
Counts can be integer or decimal:
CaCO3+(3HO1.5)2
Mass fractions use %wt, with the final portion adding to 100%:
10%wt Fe // 15% Co // Ni
Volume fractions use %vol, with the final portion adding to 100%:
10%vol Fe@8.1 // Ni@8.5
For volume fractions you have to specify the density using @density!
Mixtures can nest. The following is a 10% salt solution by weight mixed 20:80 by volume with D2O:
20%vol (10%wt NaCl@2.16 // H2O@1) // D2O@1

Absorption

1/e penetration depth(cm) absorption length(cm⁻¹) Transmission @ cm (rel.)

Macroscopic cross-sections(cm⁻¹)

absorption coherent incoherent

Scattering length density (10⁻⁶Å⁻²)

real imaginary incoherent

D2O matching density

Matching density H2O SLD(10⁻⁶Å⁻²) D2O SLD(10⁻⁶Å⁻²)

Note 1: Matching will treat T (tritium) as volatile/replaceable hydrogens.

Note 2: This uses periodictable.fasta for the calculations
