What is the transcyclic effect? What is the Closed Loop Effect?

Quaternary amine bases, nitrogen heterodoxals, enamines, and alkaloids that have transcyclic effects involving nitrogen atoms, protonation often does not occur on nitrogen atoms.

Blue Shift or Hypsochromic Shift

When the directional structure of an organic compound changes, the wavelength of the maximum absorption peak of its absorption band shifts towards a short wave, this phenomenon is called blue shift. Blue shift can also be due to the influence of substituents or solvents.

red shift or bathochromic shift

When the structure of an organic compound changes so that the wavelength of the maximum absorption peak of its absorption band shifts in the direction of a long wave, this phenomenon is called redshift. Redshift often occurs due to the introduction of co-chromophore or colored phophore into the molecule, or due to the influence of solvents. For example:

Changes in the polarity, acidity and alkalinity of the solvent, and changes in spatial structure (steric hindrance, cis-trans isomerism, transcyclic effect) can also cause changes in the ultraviolet spectrum.

Men and women standing on the suspension bridge are prone to a feeling of heartbeat due to the shaking of the suspension bridge, and it is easy to mistake it for a good impression of each other.

The research team had a beautiful young lady standing on the bridge**, waiting for men between the ages of 18 and 35 who had no female companions to cross the bridge, and told the men who crossed the bridge that she wanted him to be involved in an ongoing survey, she asked him a few questions and left him **.

Then, the same experiment was performed once on another ordinary small bridge that spanned a creek but was only 10 feet high. The same beautiful lady presented the same questionnaire to the man crossing the bridge.

The result? Apparently the men who walked across the Capinola suspension bridge thought the lady was prettier, and probably half of the men later hit her **. Of the 16 unknown male subjects who passed by on the sturdy bridge, only two had beaten her.

In a terrible environment, people are more likely to be tempted. ”

In the laboratory, Ellen once again validated his "activation theory". Have one group run for 10 minutes and compare them to the group with the same conditions but not running. After sports, people are more likely to be attracted to handsome guys and beauties on the **.

Ellen concluded from his research that any physiological "activation" could make people more tempting. Riding a roller coaster together, laughing at comedy together, or escaping a burning building together can cause emotional swings that can spark feelings for each other.

The drawbridge effect is when a person crosses a suspension bridge, their heartbeat will increase involuntarily. If you happen to meet someone of the opposite sex at this time, then he will mistake the rapid heartbeat caused by this situation as a physiological reaction caused by the other person to make his heart move.

In fact, the destruction is all around us, coal mining, paper manufacturing, battery manufacturing, the cars we drive, the incineration of garbage, the indiscriminate discharge of sewage, the massive use of plastics, the wood we use, the mobile phones we use, the sprays, the delicacies of the mountains and seas that we eat at every turn, there are too many.

Mayflies are relatively life-and-death compared to humans, and it may take a second for white blood cells to destroy the virus in the human body.

Humans are not even as good as mayflies compared to the tens of billions of ghosts who know how old they are.

Every 10 years, the virus cleanses the human race, and this 10 years may be less than a second relative to the earth, and we don't look like viruses in our bodies, and real viruses don't look like white blood cells.

Misuse of chemicals, discharge of unprocessed wastewater, uncontrolled exploitation of mineral resources, and indiscriminate felling of trees
