激光斯塔克光谱已在准直的种子超音速光束中对C10H8和C10D8分子进行了测量。在均匀电场作用下，测量了萘-H_8和-D_8的A- _1B_3u-←X_ _1AG跃迁的810带多条旋转线的斯塔克分裂和位移。测得C10H8的A 1B3u态的极化率各向异性为P‘aa−PbB=9.9(2)A3和P’BB−Pcc=6.4(2)A3，而X 1AG基态的结果为P‘aa−P’BB=6.2(2)A3和P‘BB−P’cc=7.2(2)A3。这些态之间的平均极化率的变化被确定为ΔP=P‘−P’=1.6(1)A3。C10D8的对应值分别为：P‘aa−P’BB=10.1(2)A3，P‘BB−P’cc=6.2(2)A3，P‘aa−P’BB=6.1(2)A3，P‘BB−P’cc=7.3(2)A3，ΔP=P‘−P’=1.6(1)A3。
Laser Stark spectroscopy has been performed on C10H8 and C10D8 molecules in a collimated, seeded supersonic beam. The Stark splittings and shifts of many rotational lines in the 810 band of the A 1B3u←X 1Ag transition of naphthalene–H8 and –D8 could be measured in a static homogeneous electric field. The determined polarizability anisotropies of the A 1B3u state of C10H8 are P’aa−Pbb=9.9(2) A3 and P’bb−Pcc=6.4(2) A3, whereas the X 1Ag ground state results are P‘aa−P‘bb=6.2(2) A3 and P‘bb−P‘cc=7.2(2) A3. The change of the average polarizability between these states was determined to ΔP=P’−P‘=1.6(1) A3. The corresponding values of C10D8 were found to be P’aa−P’bb=10.1(2) A3, P’bb−P’cc=6.2(2) A3, P‘aa−P‘bb=6.1(2) A3, P‘bb−P‘cc=7.3(2) A3 and ΔP=P’−P‘=1.6(1) A3.
