what I want to show you here is that 我想在这里告诉你的是
what I want to show you here is that 有时还有另一种方法
what I want to show you here is that sometimes there's an alternative way to 表示DEP T数据，例如
sometimes there's an alternative way to 再一次，如果我们在分子中运行我们的分子
sometimes there's an alternative way to express the DEP T data so for instance 模式，我们首先要将其与
express the DEP T data so for instance c NMR的自旋解耦模式
express the DEP T data so for instance again if we run our molecule in dep t 我们的样本分子成员是指
again if we run our molecule in dep t 这是我们会得到的
again if we run our molecule in dep t mode we first want to compare it to the 这种情况下，而不是覆盖
mode we first want to compare it to the 三种不同的光谱，有些是NMR
mode we first want to compare it to the spin decoupled mode of c NMR which again 只需覆盖一个，我们将
spin decoupled mode of c NMR which again 最终得到相同的信息
spin decoupled mode of c NMR which again member for our sample molecule means 我们之前见过，所以这就是我想要你
member for our sample molecule means 再次知道运行分子
member for our sample molecule means this is what we would get however in 深度模式，我们用
this is what we would get however in 自旋解耦光谱和您
this is what we would get however in this case here instead of overlaying 在此框左侧看到的是
this case here instead of overlaying 解释以下光谱的关键
this case here instead of overlaying three different spectra some NMR's just 列举任何具有负面影响的东西
three different spectra some NMR's just 峰值是由于CH2
three different spectra some NMR's just simply overlay one and we're going to 分子中恰好有一个ch2
simply overlay one and we're going to 就在这里，碳C记住了
simply overlay one and we're going to end up getting the same information that 在自旋解耦模式下该峰值
end up getting the same information that 注意在我们的叠加DPT模式下
end up getting the same information that we saw before so here's what I want you 光谱我们看到他的峰值向下或
we saw before so here's what I want you 否，如果是这样的话
we saw before so here's what I want you to know again running the molecule in 告诉我们哈尔滨是ch2
to know again running the molecule in 碳，我们也应该知道
to know again running the molecule in dep t mode we overlay this spectra with 那里没有氢的碳
dep t mode we overlay this spectra with 峰在DEP t模式下消失，因此
dep t mode we overlay this spectra with a spin decoupled spectra and what you 样本成员中的实例是B
a spin decoupled spectra and what you 没有氢的碳，他
a spin decoupled spectra and what you see here in the left in this box is the 与此信号对应的就是这里
see here in the left in this box is the 但是请注意DEP T模式下的信号
see here in the left in this box is the key to interpret the below spectra for 离开了
key to interpret the below spectra for 所以再次覆盖这两个光谱
key to interpret the below spectra for instance anything that has a negative 会告诉我们B碳必须是
instance anything that has a negative 具有雪氢的碳
instance anything that has a negative peak is due to a ch2 remember our 我们需要在这里了解的最后一件事
peak is due to a ch2 remember our 关键是CH 3和CH类型
peak is due to a ch2 remember our molecule happens to have a ch2 in it 碳在DEP T中具有正峰
molecule happens to have a ch2 in it 模式记得看一下我们的样本
molecule happens to have a ch2 in it right here it's carbon C which remember 分子碳有三个
right here it's carbon C which remember 氢附着在其上e碳
right here it's carbon C which remember is this peak in the spin decoupled mode 也有三个氢
is this peak in the spin decoupled mode D碳有一个氢
is this peak in the spin decoupled mode notice in our overlaying DPT mode 附加，所以我们将看到他们的信号
notice in our overlaying DPT mode 换句话说就是正峰
notice in our overlaying DPT mode spectra we see his peak as downward or 向上，所以这仅仅是另一个
spectra we see his peak as downward or 表达方式
spectra we see his peak as downward or negative if that's the case then that's de PT和mr数据
negative if that's the case then that's
