The asymmetric unit of the title compound, C(19)H(16)O(3), contains three independent conformers. Each of the three conformers has essentially the same feature of non-coplanar aromatic rings whereby the aroyl group at the 1-position of the naphthalene ring is twisted in a perpendicular manner to the naphthalene ring. The dihedral angles between the benzene ring planes and the naphthalene ring systems are 75.34 (7), 86.47 (7) and 76.55 (6)° in the three conformers. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds.
标题化合物C(19)H(16)O(3)的不对称单元包含三个独立的构象异构体。这三个构象异构体中的每一个都具有基本相同的非共面芳环特征，即萘环1位的芳酰基与萘环呈垂直扭曲。在这三个构象异构体中，苯环平面与萘环体系之间的二面角分别为75.34 (7)°、86.47 (7)°和76.55 (6)°。晶体结构通过分子间C-H⋯O氢键得以稳定。
