摘要：

The determinant of the adjacency-plus-distance matrix has been systematically tested for examples that would disprove a supposition that it is a unique topological index (TI) for alkanes. The analysis was carried out for alkane trees with up to 20 sites. The search was fruitful: The first pair of alkane trees with identical TI numbers was already found in the nonane family.
