[求助] 求助，怎么把這關(guān)于拉曼光譜的描述翻譯順暢

In the 250 and 1750 cm −1 region, the spectrum of MWNT-CoP 1 is dominated by the signals of the porphyrin, while the presence of MWNT is confirmed by the 2D and D+D′ bands at ～2730 and 2950 cm −1 , respectively. The spectra of the porphyrin-containing derivatives also exhibit interesting features between 2100 and 2200 cm −1 ; this region is known to be the one where the triple bond stretching mode is observed. The band at 2154 cm −1 (red spectrum) was attributed to the vibration of the protected acetylene moieties in CoP 3. After deprotection and polymerization this band disappears and gives two bands at ～2110 and 2190 cm −1 that was attributed to the ethynyl and 1,3-butadiynyl moieties,respectively.

In the 250 and 1750 cm −1 regions, the spectrum of MWNT-CoP 1 was dominated by the signals that belong to(or originate from) porphyrin, while the presence of MWNT was confirmed (signified) by the 2D and D+D′ bands at ～2730 and 2950 cm −1 , respectively. The spectra of the porphyrin-containing derivatives also exhibited interesting features between 2100 and 2200 cm −1 , a region known to have triple bond stretching. The band at 2154 cm −1 (red spectrum) was attributed to the vibration of the protected acetylene moieties in CoP 3, which disappeared after deprotection and polymerization, and gave two new bands at ～2110 and 2190 cm −1 that was attributed to the ethynyl and 1,3-butadiynyl moieties, respectively.
