GIXD patterns of bi­naphthalene thin films prepared via spin coating at spin velocities of (a) 500 r.p.m., (b) 1000 r.p.m. and (c) 6000 r.p.m. Calculated peak positions are visualized as white circles for the racemic phase with (100) contact plane and as red circles for the chiral phase with (127) contact plane. Radial line profiles of the 1000 r.p.m. sample were extracted from the (d) white annular region for the racemic phase and (e) red annular region for the chiral phase. The extracted radial line profiles are fitted assuming a racemic phase with (100) contact plane (blue) and a chiral phase consisting of unoriented (orange) and oriented crystallites with a (127) contact plane (red). Bragg peaks of both oriented components are indexed with their Laue indices. (f) The results of the quantitative analysis for the entire series are summarized in a bar chart showing the relative volume fractions of the involved components in blue, red and orange. Additionally, for each sample the total volume [{v_{{\rm{tot}}}}] relative to the sample prepared at 500 r.p.m. spin velocity is presented in black.
