IR active normal modes of methane belong to the irreducible representation:
$T_{d}$$E$$8 C_{3}$$3 C_{2}$$6 S_{4}$$6 \sigma_{d}$
$A_{1}$11111$x^{2}+y^{2}+z^{2}$
$A_{2}$111-1-1
$E$2-1200$2 z^{2}-x^{2}-y^{2}, x^{2}-y^{2}$
$T_{1}$30-11-1$R_{x}, R_{y}, R_{z}$
$T_{2}$30-1-11$x, y, z, x y, y z, z x$
(a)$E+A_{1}$
(b)$E+A_{2}$
(c)$T_{1}$
