In engineering dimensional analysis is the analysis of relationship of physical quantities with each other by identifying their base quantities or the basic units.

The normalization equation is given by,

$\underset{0}{\overset{鈭�}{鈭�}}{R}^2\left(r\right)r^{2}dr=1$

Where, R is the Radial wave function, r is the radius

Consider table 7.3, the spherical harmonic functions represented as ${螛}_{l,m_l}\left(胃\right){桅}_{m_l}\left(f\right)$are the combinations of sine, cosine and complex exponential functions and thus they are dimension less.

As you can see in Table 7.4, all radial functions have dimension$L^{-3/2}$^, because their square gives probability per unit volume.

The dimension of $P\left(r\right)$is calculated as,

$\underset{0}{\overset{鈭�}{鈭�}}{R}^2\left(r\right)r^{2}dr=1$

$\underset{0}{\overset{鈭�}{鈭�}}P\left(r\right)dr=1$

Where,$P\left(r\right)=r^2{R}^2\left(r\right)$ is the Radial Probability

Since, $dr$has the dimension of length so, the dimension of $P\left(r\right)$is$\frac{1}{L}=L^{-1}$ .
