WebOct 1, 2024 · Information Ratio - IR: The information ratio (IR) is a ratio of portfolio returns above the returns of a benchmark -- usually an index -- to the volatility of those returns. The information ratio ... WebThe infrared stretching frequencies of these groups vary in the same order, ranging from 1100 cm -1 for C-N, to 1660 cm -1 for C=N, to 2220 cm -1 for C≡N. If one of the bonded atoms (m 1 or m 2) is a hydrogen (atomic mass =1), the mass ratio in the equation is roughly unity, but for two heavier atoms it is much smaller.
