英语翻译
A combination band,νas+νs,is observed at 2462 cm-1.Two other bands appear at 1242 cm-1 and 1105 cm-1,most easily seen in the low pressure range (see inset of Figure 3),which are substantially more red-shifted compared to the gas phase values (-120 and -53 cm-1,respectively) than these of the previous bands discussed above.SO2 adsorption also induces significant changes to the frameworks vibrational modes:(1) a blue shift of the νas(COO) mode from 1639 cm-1 to 1695 cm-1 (_ν = +56 cm-1) and of the νs(COO) mode from 1433 cm-1 to 1472 cm-1 (_ν = +39 cm-1),and (2) a decrease in intensity of νas(CH2),νs(CH2) and ν(CH) modes at 2874 cm-1,2938 cm-1,and 3076 cm-1,respectively.Furthermore,the CH2 rocking mode and benzene ring deformation mode σ 12 are red-shifted by -8 cm-1 (from 830 and to 822 cm-1) and -12 cm-1 (from 744 cm-1 to 732 cm-1).The δ(COO) mode,initially at 810 cm-1 shifts to 778 cm-1 (_ν = -32 cm-1).These changes increase with SO2 adsorption.The frameworks vibrational modes assignment is summarized in Table S3.

Answer 1

一个组合带,ν+ν的,是在2462 cm-1处观察到的.另外两条带出现在1242 cm-1和1105 cm-1处,在低压力范围内最容易看到（见图3插图）,这是更多的红移,相对于气体的相位值（120和53 cm-1处,分别）比这些上面讨论的以前的乐队.SO2的吸附也引起显着的变化,对框架的振动模式：（1）的蓝移的ν作为（COO）从1639厘米到1695厘米的模式（_ν= + 56 cm-1）的νS（COO）从1433厘米到1472厘米的模式（_ν= + 39 cm-1）,和（2）强度的下降ν作为（CH2）,νS（CH2）和ν（CH）在2874厘米,2938厘米和3076厘米,分别为模式.此外,CH2摇摆模式和苯环变形模式σ12红移~ 8 cm-1的（从830到822 cm-1和12 cm-1）~（从744厘米到732厘米）.该δ（COO）模式,最初在810 cm-1处转移到778 cm-1（_ν= 32 cm-1）.这些变化与SO2的吸附增加.该框架的振动模式的任务是总
