[Tex/LaTex] Prevent extra spacing between lines from \raisebox

line-spacingraisesuperscripts

I create superscripts for indexes for notes manually with \raisebox. What I don't like is that Latex changes the line spacing to fit a manual superscript into a line. For instance: 

\documentclass{article}\usepackage{setspace}\begin{document}
\scriptsize
\parbox{3cm}{
\begin{spacing}{0.8}
TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST 
TEST TEST TEST {\tiny\raisebox{3pt}{b}}TEST TEST TEST TEST TEST 
TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST\end{spacing}}
\ \ \ \ \ \ \ \ \ 
\parbox{3cm}{
\begin{spacing}{0.8}
TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST 
TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST 
TEST TEST TEST TEST TEST TEST TEST TEST\end{spacing}}
\end{document}

creates (without the black lines)

Left \parbox with manual superscript (-> too much spacing in line before the superscript), right \parbox without (-> equal spacing).
How can I get rid of the extra spacing in the left \parbox. \raisebox can be replaced if there is a better way. It is ok if the superscript overlaps with the text in the previous line.

You need to use the (first) optional argument of \raisebox to compensate. It allows you to tell LaTeX how high the raised box officially is. So setting it to 0pt would ignore its height. There is also a second optional argument which determines the depth. The dimensions \height, \width, \depth and \totalheight can be used in all three arguments and hold the original dimensions of the content.

\documentclass{article}\usepackage{setspace}\begin{document}
\scriptsize
\parbox{3cm}{
\begin{spacing}{0.8}
TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST 
TEST TEST TEST {\tiny\raisebox{3pt}[0pt]{b}}TEST TEST TEST TEST TEST 
TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST\end{spacing}}
\ \ \ \ \ \ \ \ \ 
\parbox{3cm}{
\begin{spacing}{0.8}
TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST 
TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST 
TEST TEST TEST TEST TEST TEST TEST TEST\end{spacing}}
\end{document}
