The T-shaped NeI₂(E $0_g^{+}$) van der Waals (vdW) complexes populated in the NeI₂(E,v_E=0-2,n_E=0-2←B,19,n_B=0←X,0,n_X=0) excitation pathway have been studied. Analysis of the luminescence excitation spectra, luminescence spectra themselves and temporal behavior of the luminescence intensities of the transitions observed has been carried out. The NeI₂(E,v_E,n_E) luminescence has been discovered. This is the first direct observation of a halogen molecule vdW complex luminescence. It has also been found that lifetime of the NeI₂(E,v_E,n_E) complex depends on the v_E value: it is equal to 8 ns for the NeI₂(E,v_E=0,n_E) when vibrational predissociation (VP) is impossible and ≤ 2 ns when VP channels are open.

所述Ť形NEI ₂（Ë$0_G^{+}$）在NeI ₂（E，v _E = 0-2，n _E = 0-2← B，19，n _B = 0← X，0，n _X = 0）激发途径中填充的范德华（vdW）络合物已经研究过了。已经进行了发光激发光谱，发光光谱本身以及所观察到的跃迁的发光强度的时间行为的分析。NeI ₂（E，v _E，n _E）已经发现了发光。这是卤素分子vdW络合物发光的首次直接观察。还发现，NeI ₂（E，v _E，n _E）络合物的寿命取决于v _E值：当NeI ₂（E，v _E = 0，n _E）等于8 ns。振动预解离（VP）是不可能的，并且当VP通道打开时，≤2 ns。
