Obtained results in principle allow to determine type of
petrol in their liquid state.
There is a possibility to determine small amount of petrol in
liquid solutions.
The measurement made at low temperature (77, 4.2 K)
provide a possibility to select some PAHs for practical using
their luminescence characteristics.
Photoluminescence method can be used for remote
identification of petrol. This task must be solved in future ,
we suppose
