Möbius aromaticity
Möbius aromaticity, seen in Moebius aromatic rings, is aromatic stabilization in cyclic molecules twisted like a Möbius strip, so 4n π-electron rings are aromatic instead of 4n + 2.
Möbius carbon nanobelt
A Möbius carbon nanobelt (MCNB) is a fully fused carbon nanobelt with a half-twist, giving it a one-sided surface; the first, (25,25)MCNB, was synthesized in 2022.
Möbius function
The Möbius function, μ(n), is an arithmetic function taking values −1, 0, and 1: (−1)^k for products of k distinct primes, and 0 on non-squarefree integers.
Möbius inversion formula
The Möbius inversion formula, also called Möbius inversion, is a number theory theorem stating that if f(n) is the divisor sum of g(n), then g is recovered using the Möbius function.
Möbius strip
The Möbius strip, also called the Möbius band, is a surface with only one side and one edge, made by joining a strip with a half-twist.
