a.u. > 2 is outside the dynamic range of many spectrometer anyway and so
two
of your spectra are not really meaningful to start with.
the two spectra with weaker absorption are meaningful and do have some
features around 330-400 nm. your baseline is terrible (should be close to
0). Either your control (i assume you used a dual beam uv-vis) is bad, or
like someone said you've lots of scattering which caused light loss.

我的拍卖回来的kia spectra左转向灯闪得很快且只有一根丝亮,因为还在保
修期内,开到dealer那修。小伙把车开到后车库,不让我跟进去看;一会他们
叫我进去说要75刀一小时的费用检查问题,查出问题后他们再决定在不在保修
范围内。我拒绝了,一伙计带我出来,不允许我待在里面看他们把车灯装回去。
当时我已经非常后悔把车开到dealer那去,先交$75/小时的检查费说明
warranty完全是骗人的。我看过“修车十大宰”这篇文章,心有余悸。
回来几天后发现雨刷不能喷水了(之前能喷的)。和我的做二手车生意的非洲邻
居聊起此事,他说dealer需要你不停地回去找他们修来房租,工资...
现在2个问题还在。网上说查查接地线的接触,下午搞了半天拆不下left side
lower panel。
雨刷不能喷水可能是因为喷水口被堵了。不过我找不到喷水口。
