为了从实验上确认激光解离正十二烷Ｃ６－Ｃ７键的可行性，通过多光子吸收的非线性光学效应，用３０８ｎｍ波长的氯化氙激光对正十二烷进行先解离实验。利用气相色谱技术分别获得了正十二烷原样，解离产物及其剩余物的气相色谱图，经过综合分析表明相对于原样在产物和剩余物中正十二烷的含量减少，而其中的正己烷和己烯—１的含量相对增多。此结果经讨论排除了可能存在的其它因素，确认正十二烷已被激光解离。
In order to experimentally confirm the feasibility of laser dissociation of n-dodecyl C6-C7 bonds, n-dodecane was first dissociated with a 308 nm wavelength of xenon laser using non-linear optical effects of multiphoton absorption. The gas chromatograms of n-dodecane, dissociation products and their residues were obtained by gas chromatography. The comprehensive analysis showed that the content of n-dodecane in the product and the residue decreased compared with that of n-hexane And hexene-1 content relative increase. This result was discussed after excluding other factors that may exist to confirm n-dodecane has been laser dissociation.
