TL;DR: In this paper, β-cyclodextrin (β-CD) has been found to form inclusion complexes with 1-methylnaphthalene, 1-ethylnaphthylene, 1-(chloromethyl)naphthyne, and 2-ethyl naphthylene, and the excimer fluorescence is concluded to be due to a 2 : 2 β-CD-alkylnaphorthene inclusion complex.
Abstract: In aqueous solutions, β-cyclodextrin (β-CD) has been found to form inclusion complexes with 1-methylnaphthalene, 1-ethylnaphthalene, 1-(chloromethyl)naphthalene, and 2-ethylnaphthalene. Addition of β-CD to aqueous solutions of 1-methylnaphthalene and 2-ethylnaphthalene has resulted in the observation of the excimer fluorescence of each compound. From simulations of the observed excimer fluorescence intensities of 1-methylnaphthalene and 2-ethylnaphthalene, the excimer fluorescence is concluded to be due to a 2 : 2 β-CD–alkylnaphthalene inclusion complex. In the cases of 1-ethylnaphthalene and 1-(chloromethyl)naphthalene, the excimer formation within the β-CD cavities seems to be prohibited due to the steric hindrance caused by a substituent, although the 2 : 2 β-CD–alkylnaphthalene inclusion complex is likely to be formed. Equilibrium constants for the formation of these 1 : 1 and 2 : 2 inclusion complexes have been evaluated from the monomer and excimer fluorescence intensity changes with β-CD concentration.

TL;DR: In this paper, the excimer light is applied to a reduction projection exposure device with a reflection system as a main body, thus exposing photo resist through a photo mask, and a reflection film is provided on the other outer end face.
Abstract: PURPOSE:To improve the resolution of a projection optical system with a reflection system as a main body by exciting at least one type of gas which is selected from xenon, krypton, and argon, using a dielectric barrier discharge lamp utilizing excimer emission which is discharged from the excitation gas for exposing photo resist. CONSTITUTION:An annular inner space 1 is a discharge space, xenon, argon, krypton, or a mixture gas of krypton and chlorine are filled inside, and discharge excitation is performed by an AC power supply 6, thus obtaining excimer light from the filled gas. Since excimer light is obtained from one end face 7, a reflection film 9 of aluminum is provided on the other outer end face 8. Further, a mask means for shaping the excimer light in dot shape or straight line shape or one part of ring is provided at the end face 7 for taking out excimer light or at its front. Then. the excimer light is applied to a reduction projection exposure device with the reflection system as a main body. thus exposing photo resist through a photo mask.

TL;DR: In this paper, Koopmans' theorem level calculations of the electron binding energies in excited state anions of several polar diatomic molecules have been performed, and binding energies as small as 5 × 10 −8 eV (for the fifth) excited state of MgO − ) were obtained.
