Good morning, dear friends, I would like to inform you about a fragrance that I loved before, but whose name I do not know. The smell that emerges when it combines with the soil when it rains is a good smell for most people. Now let me give information about how that smell is formed and let me tell you what the name of that smell is. When the rain meets the soil, a chemical cocktail emerges. The cocktail that causes the smell after rain and contains many chemicals from vegetable oils to minerals is called Petrichor.
