| 對實驗數(shù)據(jù)進(jìn)行分析發(fā)現(xiàn)在降溫過程中A分子和B分子的分子內(nèi)氫鍵及分子內(nèi)氫鍵之間的競爭行為引起了A的S=O雙鍵和B分子的O-H鍵的拉曼譜帶的變化。進(jìn)一步分析表明：在27℃至-30℃降溫過程A與B之間氫鍵加強(qiáng)，-30℃至-60℃降溫過程A與A之間氫鍵代替A與B之間的氫鍵。這為豐富溶液的氫鍵理論提供了實驗依據(jù)。 |

| From the analysis of the experimental data it is observed that the competition behavior of intramolecular hydrogen bond between A molecule and B molecule as well as intramolecular hydrogen bond themselves leads to the variation of raman band of the S=O double bond of A molecule and O=H bond of B molecule in the cooling process.Further analysis indicates hydrogen bond between A and B was reinforced in the cooling process from 27℃ to -30℃ while hydrogen bond between A and A was replaced by hydrogen bond between A and B in the cooling process from -30℃to -60℃, which provides experimental basis for enriching hydrogen bond of solution. |

Through the analysis of the experimental data i found intramolecular hydrogen bond of A molecule and B molecule and the change of Raman spectrum band of the S=O double bond of A molecule and O=H bond of B molecule by the competative behavior of intramolecular hydrogen bond in the process of temperature drop. Further analysis shows that : hydrogen bond between A and B strengthened during the 27- (-30℃） temperature drop, the hydrogen bond between A and A replace hydrogen bond of A and B during the -30~-60℃ temperature drop process. And this provides a scientific basis for the enrich of hodrogen theory of solution . 外行翻譯的，見笑了。句子有點長，不是很好翻譯。 |

it is observed that the change of Raman spectrum band of the S=O double of A molecule and O-H bond of B molecule by the analysis of the experimental data, due to the competition behavior of intramolecular hydrogen bond of A molecule and B molecule. Futher analysis indacates that indicates hydrogen bond between A and B was reinforced in the cooling process from 27℃ to -30℃ while hydrogen bond between A and A was replaced by hydrogen bond between A and B in the cooling process from -30℃to -60℃, And this provides a theory basis for the enrich of hodrogen bond of solution . |
