USEFUL FORMULAS

Max Q

Calculation

\(Q = \frac{2{\pi}sin(2\theta)}{\lambda}\)

\(2\theta\) = angle

\({\lambda}\) = wavelength

example:

\(Q = \frac{2{\pi}sin(5)}{7.5}\) = .073 Å-1

Opacity

Calculation

\(\frac{opacity(\lambda_1)}{\lambda_1}\) = \(\frac{opacity(\lambda_2)}{\lambda_2}\)

opacity = n\(\sigma\)l

This is given for a specific cell optimized for a given \({\lambda}\)

example:

Burgundy is a 5 Å cell

calc. opacity for 6 Å expt.

\(\frac{x}{6 Å}\) = \(\frac{3.138 Å}{5 Å}\)

x = 3.766 opacity
