$H^{\frac{3}{2}-\epsilon}\left(\Omega\right)\hookrightarrow\hookrightarrow H^{1}\left(\Omega\right)$ for $\epsilon\in\left(0,\frac{1}{2}\right)$?

Question

I need know if $H^{\frac{3}{2}-\epsilon}\left(\Omega\right)\hookrightarrow\hookrightarrow H^{1}\left(\Omega\right)$, for $\epsilon\in\left(0,\frac{1}{2}\right)$ and $\Omega$ a bounded domain in $\mathbb{R}^{n}$, with $n=2,3$. Well, I don't know a good book for theorems of compact embeddings between Fractional Sobolev Spaces ($W^{s_{1},p}\left(\Omega\right)\hookrightarrow\hookrightarrow W^{s_{2},q}\left(\Omega\right)$ ?). Any reference?
