Crystal structure of normal alkanes has an odd-even effect in a bulk phase. In the present study, films of alkanes are prepared by the spin-coating technique and the assembling molecular structure the thin film has been revealed by using the pMAIRS technique. Regardless of length of alkyl chains, alkanes have a perpendicular stance in the thin film.
The odd-numbered alkanes exhibit more vertically orientation than the even-numbered alkanes.
