报道了一种新的技术--IR-IR-UV烧孔技术，当电子光谱重叠太近而不能通过标准的离子浸渍或荧光浸渍方法获得不受其他构象干扰的干净光谱时，可以获得构象特定的红外光谱。以4‘-氨基苯并-15-冠-5-醚-(HDO)络合物为例，用该方法证明了存在两个电子光谱重叠的构象，并对同一构象的红外光谱跃迁进行了归属。
A new technique, IR-IR-UV hole-burning, is reported for obtaining conformation specific IR spectra when the electronic spectra are too closely overlapped to obtain clean spectra free from interference from other conformations via standard ion dip or fluorescence dip methods. The 4'-aminobenzo-15-crown-5 ether-(HDO) complex is used as an example, on which the method was applied to prove the presence of two conformations having overlapped electronic spectra and to assign IR transitions belonging to the same conformation.
