H2对CO红外吸收系数的影响

用NICOLET 170 SX型付里叶变换红外光谱仪,研究了H_2对CO红外吸收系数的影响,测定了在7托CO中加入0—450托H_2时,CO(?)P(6)、R(5)线的吸收系数的变化.并进行了讨论.实验还测定了纯CO P(6)、R(5)、P(9)、R(9)线的吸收系数,并考察了满足比耳定律的浓度范围.

EFFECT OF H2 ON THE ABSORPTION COEFFICIENTS OF CO AT IR REGION

Effect of H2 on the absorption coefficients have been investigated with Nicolet 170sx FTIR spectroscopy. The variation of absorption coefficients of P(6) and R(5) lines of CO has been observed while 0-450 torr H2 was added to 7 torr of CO. The absorption coefficients of P(6), R(5), P(9) and R(9) lines of pure CO have been determined, and the concentration ranges in which Beer's law is suitable have also been examined.
