  In this article, we propose a novel technique to test for anomalous features
in the CMB. We analyse separations of the observed CMB angular power spectrum
($C_\ell$) using temperature anisotropy data from WMAP 9 year ILC and 2018
Planck maps of Commander, NILC and SMICA. We estimate the minimum, maximum,
average separations and ratios of the maximum to minimum separations between
consecutive multipoles of the weighted spectrum, $f(\ell)C_{\ell}$. We see that
such $f(\ell)$'s with higher multipole powers mitigate the parity asymmetry
anomaly. For anomalous separations, we find that data exhibits anomalous ranges
of multipoles defined by different $\ell_{max}$ and $\ell_{min}$ values,
specifically for the entire range of multipoles from $2-31$ of this work.
Without parity based distinctions, most significantly, the maximum separation
of the range $8\leq\ell\leq31$ is seen to be anomalously low at the $99.93\%$
confidence level for $f(\ell)=\ell$ (WMAP), $\frac{\ell(\ell+1)}{2\pi}$ (Planck
NILC), the latter indicating a strong deviation from the Sachs-Wolfe plateau
for maximum separations among low multipoles. The analysis is repeated for odd
and even multipoles taken separately, in the same multipole ranges. Most
noticeably, the even multipoles are seen to have anomalously low maximum and
average separations relative to their odd counterparts, the most outstanding
among which is the anomalously low maximum separation for even multipoles in
the range $6\leq\ell\leq31$ for $f(\ell)=\ell$ (WMAP), at the $99.77\%$
confidence level. For separation ratios, the multipole ranges are similar to
those which turn up as anomalous when only separations are considered.
