The spectra of C₁ molecules are confounding in that each of the fundamental vibrational modes transform as the same irreducible representation (A) and hence each band consists of a seemingly random distribution of a-, b-, and c-type transitions. This is in contrast to higher symmetry molecules for which band types are readily deduced by simple symmetry rules. Herein, we present a method to simulate the convoluted rotational contours in the gas-phase spectra of C₁ molecules by combining existing ab initio calculations with Colin Western’s pgopher rotational contour program. Specifically, ab initio calculations in the NWC hem suite of programs were employed to predict the components of the dipole moment derivatives along the principal axes of the moments of inertia. This information was then input into pgopher to model the fundamental band contours as a sum of a-, b-, and c-type transitions. This method was applied to simulate the rotational contour spectra of a series of representative C₁ molecules which were then compared against both ab initio stick spectra and experimentally measured broadband IR spectra from the Pacific Northwest National Laboratory infrared gas-phase database. In addition to providing further insight beyond what is revealed in a typical stick spectrum, the simulated contours showed good agreement with the measured spectra.

It’s pretty hard to imagine the world through someone else’s eyes, especially different animals. But a new study using lab-grown human retinas reveals that even between different humans, our vision is extremely diverse.

And it might be to do with how the red and green cones form in our retinas. Cones are light-sensing cells in vertebrates’ eyes; their combined responses to different wavelengths enable color vision.

Humans and some closely related primates are some of the only mammals known that can see the color red, as well as green and blue.

A gigantic trove of passwords has been released by bad actors, and there’s a very good chance that yours is on there.

According to Troy Hunt, the man behind the excellent breach notification site “Have I Been Pwned” — which allows users to look up your email and see if and where your passwords and other user information have been compromised — it’s one of the largest collections of breached data he’s ever seen appear online.

To a data defender like Hunt, “large” is not an understatement. The cache of files, dubbed “Naz. API,” contains more than 71 million email addresses and 100 million passwords. Thus far, more than 400,000 Have I Been Pwned (HIBP) subscribers have been impacted.

An enlarged prostate is when the prostate gland becomes larger than normal causing symptoms that can slow or block the flow of urine out of the bladder. It is also called benign prostatic hyperplasia (BPH). Learn more about symptoms, diagnosis and treatment:
