The wavelength dependence of the neutron absorption cross section of hydrogen in [ReH 3 (C 2 H 4 ) 2 {P(i‐Pr) 2 Ph} 2 ] was investigated by recording the decrease in Bragg peak intensity from a standard NaC1 crystal caused by attenuation of the incident beam by the Re sample. Data were collected on the Single Crystal Diffractometer (SCD) at the Intense Pulsed Neutron Source (IPNS, Argonne National Laboratory) which enabled concurrent measurements at a selection of wavelengths using the time‐of‐flight technique.
